The other is a private key that you use to decrypt messages that you receive" (Pretty pp).
PGP is such an effective encryption tool that the United States Government actually brought a lawsuit against Zimmerman for putting it in the public domain and therefore making it available to enemies of the United States, however, after a public outcry, the government's lawsuit was dropped, yet it is still illegal to use PGP in many other countries (Pretty pp).
To encrypt a message using PGP, you need the PGP encryption package, which is available for free from a number of sources, however the official repository is at the Massachusetts Institute of Technology (Pretty pp).
PGP or Pretty Good Privacy is a powerful cryptographic product family that enables individuals to securely exchange messages, and to secure files, disk volumes and network connections with both privacy and strong authentication (elcome pp). By providing the…… [Read More]
PGP Encryption, better known as Pretty Good Privacy is a computer program that provides cryptographic privacy and authentication. Phil Zimmerman, the developer of PGP, introduced his invention in 1991. Since then, major improvements have been made to the computer program and is now available from PGP Corporation and other companies.
The original intent of PGP was to encrypt email and attachments. PGP encryption applications have expanded to a variety of components including laptop full disk encryption, digital signatures, protection for instant messaging sessions, file and folder security, files and folders stored on network servers, email and attachments and batch file transfer encryption.
The origin of PGP
PGP was first brought to the public in 1991. From 1991 to 2012, quite a few versions of PGP as well as several organizations or companies have maintained control of PGP. PGP was free on its first release to the public but once PGP…… [Read More]
With the ever-increasing amount of information traffic on the net (LAN, WAN, etc.) there is a corresponding increase in the risk of vital data falling into the wrong hands. Data encryption is a technology that provides for a safe, secure and private information exchange.
The advancement of computer technology has bought a paradigm shift to our mode of communication. The Internet has managed to overcome all the geographical limitations and reduced the whole world to sort of a global village. The Internet has bought a whole new perspective into all walks of life. We are in a period where increasingly businesses are getting done online. The unprecedented growth of Internet and the global market that it promises has driven businesses all over to world to into ecommerce. Today most businesses carry their transactions online. This new technological revolution however is not without its loopholes. Hackers are on the increase…… [Read More]
This is however, not considered foolproof. It is possible to break the security by a person having adequate technical expertise and access to the network at hardware level. In view of this the SSL method with right configuration is considered perfectly sufficient for all commercial purposes.5In order to safeguard the data while in transit it is customary to adopt a practical SSL protocol covering all network services that use TCP/IP to support typical application tasks of communication between servers and clients. (Secure Socket Layer- (www.windowsecurity.com)
Communication over the internet passes through multiple program layers on a server prior to actually getting to the requested data like web page or cgi scripts. The requests first hit the outer layers. The high level protocols like HTTP that is the web server, IMAP -- the mail server, and FTP the file transfer are included as outer layer protocol. Determination of the outer layer…… [Read More]
Institute of esearch: Different Types of Encryption
Keeping data secure is of particular concern for healthcare organizations committed to patient research. Patients are often concerned about being forthcoming about their information because they fear it may be used against them when making occupationally-related decisions or setting health insurance premiums. Organizations must not simply be vigilant in ensuring that such information is protected; they must avoid the appearance of being careless. The creators of the ABC security system must be diligent in ensuring that there are a series of impenetrable controls to ensure that only authorized personnel have access to sensitive information. The most commonly-used method to protect electronic data is that of encryption. "Encryption uses mathematical formulas to scramble data, converting sensitive details coveted by intruders into gibberish" (Behrens 2015). Two techniques are available to protect data for the ABC Institute and its collaborator XYZ, that of "symmetric encryption (also…… [Read More]
Symmetric Encryption and Asymmetric Encryption Technology
On the VM (virtual machine) in the university virtual lab, there consists a folder named "c:encrypt." The folder consists of two files:
img.jpg, and "encrypt.exe -- encrypt and decrypt key."
This paper decrypts the picture to view the text hidden in the picture.
Objective of this project is to discuss the encryption technology strategy used for the software application.
Encryption Technology Strategy used for the Software Application
In the IT (information technology) environment, the symmetric encryption and asymmetric encryption technology are used to encrypt and decrypt a text or message. However, the asymmetric is the encryption technology used to encrypt the text inside the img.jpg file. The asymmetric encryption uses the two keys for the asymmetric cipher, and the two keys consist of a private and public key. In essence, the public key is available for everybody where the private key is only known…… [Read More]
Mail Server and iPhone 6 Encryption
Email is very critical for business communication, although, many businesses organizations outsource their web-based services such as Google Apps or iCloud, however, these services are not a good option for businesses in possession of the critical data. Moreover, some organizations claim that the outsourced business emails are costs effective than hosting a private email server, nevertheless, the benefits of hosting private email servers outnumber its shortcomings. For example, it is not businesswise to trust a third party to safeguard sensitive business data, and if the data is compromised or stolen by hackers, the organization can face the risk of lawsuits, court fines and consequent loss of revenue. Thus, it is beneficial for organizations to develop their email servers rather than allowing a third party to manage their emails.
The objective of this paper is to demonstrate the benefits that organizations can derive from hosting…… [Read More]
weaknesses of the Data Encryption Standard (DES).
The Data Encryption Standard (DES) was a system developed by the USD government for use by the general public. Accepted both by the U.S. And abroad, many hardware and software systems employ the DES. Both individuals can send and encrypt and decrypt information to and from the other. The symmetry of the situation makes this a popular key. Authenticity is guaranteed since only the sender can produce a message that will encrypt with the shared key (Paar, & Pelzl, 2009). However the DES is also riddled by various weaknesses (Pfleeger & Pfleeger, 2007).
Firstly and, perhaps, most importantly, security is a major concern. Whilst issues have been more or less resolved regarding the design's secrecy and that certain 'trapdoors' had been embedded in the DES algorithm enabling easy means to decrypt the message, many analysts are still concerned about the number of iterations…… [Read More]
General Packet Radio Services (GPRS) is a service used in the provision of packet radio access for the GSM (for Global System for Mobile Communications) users .In regard to the wireless component, the GPRS technology makes a reservation of the radio resources only in instances when there are instances of data to be sent over its infrastructure. This therefore ensures that the radio resources are optimized. The fixed part of the GPRS infrastructure employs Internet Protocol (IP) technology as is usually connected to the general public internet. By taking advantage of these resources, the GPRS infrastructure manages to provide a variety of applications and services that are packet-oriented to the mobile end-users and therefore making a reality the concept of mobile internet services. For the successful implementation of these services as well as other news immerging services and applications over the GPRS infrastructure, security is paramount .This is due to…… [Read More]
The author of this report has been charged with, after having selected, the subject of Wi-Fi vulnerabilities, what to know about them and what to do about them. While using safe and secure Wi-Fi is not always possible, it is usually possible to use one or more means to avoid having data being compromised as it travels through the air. The issues that will be covered in this report include what protocols are best, what protocols should be avoided, how speeds can come into the calculation and so forth. While dangers exist out there when it comes to using Wi-Fi data, a little preparation and thinking in advance can prevent or at least mitigate a lot of problems.
The first thing that will be discussed does not have much to do with safety online but it certainly has an effect on productivity and how long it…… [Read More]
Onion Routing uses a flexible communications infrastructure that prevents traffic from being analyzed and eavesdropping from occurring. The way it works is by separating routing from identification techniques. In other words, any identifying information is removed from the data stream (Syverson, 2005).
The structure is created by wrapping a plaintext message in layers of encryption. Just as an onion has layers that peel away, this wrapping is successively pealed away as the wrapped message is passed through from one router to the next. The message is viewable only by the sender and the recipient and perhaps even the last node, unless end-to-end encryption is used (Joshi, 2012).
For example, in a packet switched network, packets use a header for routing and the payload confers the data. The header is visible to the network and anyone watching the network; it tells where the packet originated and where it is going.…… [Read More]
(Proposed encryption, 2004, USA Today). As Bruce Schneier's text Schneier on Security indicates, encryption is being increasingly used by watchful and responsible people to protect their security online. The concern about implicating an innocent person or giving a harsh sentence to someone for a minor offense is not far-fetched given the ubiquitous nature of encryption technology. The useful and benign nature of encryption means that to increase the potential penalties for a crime simply for using encryption may allow many small and possibly great injustices to occur within the judicial system.
Proposed encryption laws could prove draconian, many fear. (2003, March 31). USA Today.

but, just because other countries have weaker standards doesn't necessarily mean that the U.S. should. Walker quotes an Electronic Frontier Canada representative as saying that, "Export controls have had the general result of weakening the encryption standards available off the shelf in the U.S. And Canada." To her credit, Walker provides an alternative view by a senior officer of a security vendor saying that existing encryption, digital signatures and strong authentication technology make it save to do business on the Internet. The problem is that both of these sources are biased and there's not enough evidence to support or dispute either one.
Walker never answers the question she initially posed in the title of her article, "How Much Encryption Do We Need?" The article is filled with unsupported generalizations and opinions and can no way be considered an authoritative research source.

Part 2 - Reflective Diary
The security of customer's data is very critical in the contemporary business environment because of the increase in the data breach that could make organizations to face bad publicity within and outside the United States. Essentially, organizations are required to secure employees' and customers' data to enhance Pretty Good Privacy (PGP) within the IT environment. One of the strategies to enhance customers' privacy is to implement data encryption. Encryption is a strategy of encoding data file where only authorized user can only have access to a secret "key' in order to read the data. The major impact of encryption is that it will prevent unauthorized access to organizational data, which will consequently enhance data protection and privacy. oreover, securing information will make organization to be in line with the IT ethical standard, which will consequently enhance organizational public image.

4G LTE Encryption
When cellular phones first came out, the concerns about data loss and theft was not all that high. This was mostly because these devices functioned mostly (if not entirely) as phones with perhaps a camera phone here and there. Nowadays, however, cellular phones are often smartphones and they are literally small computers in terms of the data that they carry and the abilities that they have. Given that and the fact that tablets and other devices have entered the cellular signal fray, it is important to focus on the data security that these data devices have and whether that technology is being used in the way it could or should be and whether improvements are needed. While technology and encryption have come a long way, it is imperative that the envelope is pressed harder and harder every day so as to maintain (or create) privacy and safety…… [Read More]

Securing the Electronic Frontier
The paradox of how to secure individuals and organizations' right to access the Internet vs. securing personal and corporate data and identities is a particularly complex and challenging issue. The ethicacy of this paradox is most present in the differences between encryption and Pretty Good Privacy (PGP). Too open of standards and governance policies on these areas will often lead to large scale data breaches, as many organizations presume they have greater security over their data than is actually the case (Mikko, 2010). When security guidelines and initiatives are too restrictive, organizations cannot accomplish their objectives either. Making this paradox complex is the ethicacy of asking people and organizations for passwords and access to their accounts (Spinello, 2004). The ethics of trespass vs. legitimate access becomes all the more critical when the complexity, pace and severity of computer fraud perpetrated by globally-based gangs that are well-financed…… [Read More]
Senior leadership of a medical center has just recently reviewed the plan for changes to the center's facilities. However, the medical center found out that the associated risks related to the new and emerging technologies had not been addressed. Thus, the Hospital's Chief Operating Officer (COO) has given a Chief Information Security Officer (CISO) two weeks to deliver a quick evaluation of the risks as well as the planned expansion of the areas that may pose potential technology problems.

In reality, the concept of intrusion detection systems is a straightforward matter of designing a system that can provide alerts when it is attacked. According to Andress (2003), the process of intrusion detection typically requires the identification of unauthorized access into computer systems.

This is very important in the securing of communication taking place over the open systems like the internet. This is done by embedding hidden information in data packets that are being conveyed over the TCP/IP link. The information is embedded in audio, video or even in pictures that are being sent over the link.
Digital watermarking involves the use of steganographic techniques to effectively embed information into various documents. This is important for copywriting reasons by corporations. Digital watermarking is then used in embedding a company's copyright into the property of a company. This is then used in prosecuting pirates as well as digital thieves. The copyright or trademark information is embedded in the copyrighted image, audio or video files.

Like all other aspects of business today, security systems often prove to be highly complex and hard (even for the participants) to identify.
The culture of an organization is like the culture of a family, a community, or a nation: Because it surrounds the people in it they often have a great deal of difficulty in recognizing to what extent policies and procedures arise from the constraints of culture and what therefore can be relatively easily changed. Matz (2010) summarizes the ways in which organizational culture both supports an organization and can blind the individuals in it to ways in which their actions may no longer be as effective as they once were:
… the essence of organisational cultures consists of a set of 'unspoken rules' that exist without conscious knowledge of the members of the organisation. Over time the invisibility of the attributes at the deepest level…… [Read More]
Despite of these advantages that were mentioned, which creates the power to convince consumers and business owners to use and accept legacy payment methods in a networked environment, there are also a number of disadvantages why some people are hesitant to use such mode of payment. They are especially true when they are used in a networked environment particularly in the Internet.
Issues, Disadvantages, and Solutions in Legacy Payment Methods in a Networked Environment
One of the most critical issues that exist in the use of legacy payment methods in a networked environment, such as the credit card, is how secured are the financial and personal information of the credit card users. Especially when used online, where information is oftentimes vulnerable to threats and unauthorized access, there is a high possibility that credit card information may not be secured. This thus is causing great concerns for consumers.

Government officials and elected officers become unwilling to provide limited public funds to broadcasters whose audiences are becoming smaller, forcing public service programmers to reach for larger audiences with different types of program content.

The problem is stated clearly by Graham: "The legal community has paid little attention to the consequences for individual privacy of the development of computers" (Graham 1987, p. 1396). Graham does say that the common law has the capacity to protect privacy rights from invasion of privacy just as it expanded to combat threats in the past, but he also says that privacy law has lagged behind technology: "Privacy law has failed to respond, as it has in the past, to technological changes that influence the degree of privacy to which we are accustomed" (Graham 1987, p. 1396).
Technology has changed the nature of "privacy" according to some because technology has altered the meaning of "public." In an earlier age, people possessed greater anonymity than in the computer age, given that information is increasing with vast stores of data about everyone accessible by computer. The old concept of privacy…… [Read More]

In addition electronic purses can be reloaded using ATM machines or traditional tellers (if the card is connected to a banking account).
Additionally, electronic purses are usually based on smart card technology and necessitate a card reader to fulfill a transaction. Equipment including point of sale (POS) terminals, ATMs, and smart card kiosks can be outfitted with card readers (Misra et al., 2004). Every time the user utilizes the card reader to complete a transaction; the card reader will debit or credit the transaction value from or to the card.
The author further asserts that Smart cards can be utilized for various purposes.
In most cases they are used as stored value cards (Misra et al., 2004). Stored value cards can be utilized at the time of purchase and are preloaded with a certain amount of money. These cards can be discarded after they have been used; however, most stored…… [Read More]
In order to maintain information secrecy one would use cryptography. This is intentionally making information unintelligible. This method is mainly employed during the transmission of information. Cryptography ensures that only the intended person would be able to decipher the information (Whitman & Mattord, 2011, p. 339). The process of deciphering encrypted text is referred to as cryptanalysis. Cryptology is the mathematics branch covering cryptography and cryptanalysis. Cryptology has been in use since 1900 B.C. In Egyptian hieroglyphs. A Mesopotamian cryptography was discovered in 1500 B.C. that surpassed that of the Egyptians. The book of Jeremiah was written using alphabet substitution called ATBASH. Cryptography was employed during the First World War to decipher radio communication. Prisoners have also used cryptography to decipher their messages in order to protect their privacy. A key in cryptography is a parameter or piece of information that would determine the functional output for a…… [Read More]

"Unlike IP fragmentation (which can be done by intermediate devices), IP reassembly can be done only at the final destination. What problems do you see if IP reassembly is attempted in intermediate devices like routers?" [ ]
IP fragmentation is defined as the IP (Internet Protocol) that breaks datagrams into smaller fragment to assist packets passing through links and forming a smaller MTU (maximum transmission unit) than its original size. However, the fragments reassemble themselves when reaching the receiving hosts. After the receiving hosts have received the fragmented IP packet, they have to reassemble the datagram before passing it to the higher layer. In practices, the reassembly happens in the receiving hosts, however, a reassembly may be carried out by the intermediate router. For example, the NAT (network address translation) is designed to reassemble the fragments to the translate data streams.…… [Read More]
Abstract - With regard to security, the major issue is that most mobile devices are targets that are in line to face attacks. Mobile devices face a range of threats that capitalize on several susceptibilities usually obtained in such devices. Lack of encryptions is a major threat to security of mobile device networks. Information such as text messages and electronic messages that are sent using a mobile device are more often than not unencrypted. Furthermore, numerous mobile device applications lack such encryptions over the networks for transmission and reception and therefore simplify the process of data interception. Malware is an additional problem regarding mobile device networks. It is simple for mobile device users to download malware through games and security patches and also through online advertisements. Consequently, this makes it significantly easy for data interception owing to spyware and Trojans. The lack of security software is also a major issue.…… [Read More]
Secured real time protocol (STP) is also being identified to enhance the security parameter of WAN and LAN network elements. "STP provides protection with encryption keys for wired and wireless networks including bandwidth limited channels." (Guillen and Chacon 2009 P. 690). There is also a growing use of IP secure to protect organization from the interception of data over the LAN and WAN environment.
To enhance network security, Chen, Horng, & Yang (2008) postulate the use of public key cryptography. While there is a growing use of public key cryptography, there is still a shortcoming identified with the use of public key cryptography in the LAN and WAN environment. Since the public key is being kept in a public file, it is possible for an active intruder to forge the contents of the public key and use it to get access onto the data kept within the network system. To…… [Read More]
Network Security and Why Use It
Security And Why Use It
The security of any network should be taken seriously. A network allows someone to share resources and information with others on the network. Networks allow for distribution of computer viruses, Trojans, human intruders, and employees can damage more than just one computer. To better understand the importance of network security, one needs to think of what might happen if all the data for a company that is stored in their servers vanishes. This scenario would cause losses that the company might never recover. Networks are divided into three main categories Internetwork (internet), Wide Area Networks (WAN) and Local Area Networks (LAN). These three categories of network require security to ensure that no malicious humans gain access, and no viruses attack the network.
To better understand network security, one needs to know what a network is. A network is defined…… [Read More]

features of telecommunications networks, including key networking technologies. Cover the Open Systems Interconnection (OSI) model, including each logical layer.
The OSI layer covers the different layers and types of communication that occurs within a network. The layers, in order of complexity from greatest to lowest are application, presentation, session, transport, network, data link and physical. The physical layer is the actual transport medium like network cable and such while routers and switches address much of the middle layers while the "window" to the user is the application layer at the very top. Telecommoniciation networks, and this is something that will be answered more in-depth later in this report, are very computer driven and are in many ways indistinguishable from regular computer networks as phone and conventional internet networks are very much one and the same and this is especially true when speaking Voice over IP (VOIP) technologies and the like.…… [Read More]
Security Audit for FX Hospital EH/EM Systems
The study carries out the security audits for the FX Hospital EH/EM information systems to identify the vulnerabilities in the systems. The study uses the BackTrack as an auditing tool to penetrate the website, and outcomes of the auditing reveal that the website is not secure and can be subject to different vulnerabilities. After carrying out the auditing, the study is able to collect as much patients' data as possible revealing the website can be subject to vulnerable attacks. One of the vulnerabilities identified is that the website UL starts from HTTP showing that an attacker can easily break into the website and collect sensitive information. Moreover, all the data in the website are not encrypted making them easy for an attacker to collect patients' data.
By consequence, the FX Hospital can face lawsuits for failing to protect patients' data because if patients'…… [Read More]

Terrorist organizations and terrorists are exploiting social media and the internet resources for the purpose of committing terrorist activities and for the facilitation of wide-ranging terrorist activities including radicalization, incitement, training, recruitment, communications, information gathering, planning, financing, and preparation (United Nations, n.d). Technology has quickly become a fundamental component of the modern day society. Technology governs itself therefore making it possible for terrorists to utilize it for the purpose of advancing their terrorism. Modern terrorism has become unpredictable and instantaneous thanks to technology. Technology has made it possible for terrorists to target large audiences and bring terror right into the home (InfoSec, 2018). Cyberspace is a technological environment that has no boundaries hence making it a place where terrorists can locate resources, disseminate propaganda information and launch attacks in any corner of the world.

Review of the Literature.
Security Risks Associated with IEEE WLAN 802.11. The applications for wireless communication technology continue to develop and expand; today, at least, the 802.11b is the standard of choice for wireless router communication used with network installation (Gonazles & Higby 2003). "The integrity of the transmitted data is a valid 2.4 GHz. At this wavelength medium, the propagation of wavelength maintains strong connectivity" (Gonzales & Higby 2003, p. 30). The technology of WLANs actually dates back to the mid-1980s; during this period, the Federal Communications Commission (FCC) freed up radio frequency (rf) to the industry. "Initially, this was viewed as a broadcast reception procedure and very little thought went to broadcast transmission" (Gonzales & Higby 2003, p. 30).…… [Read More]

TMP (Trusted Platform Module) is an international standard dedicated to secure hardware by integrating the security cryptographic keys into hardware devices. In other words, the TMP is a secure cryptoprocessor integrated into the computer motherboards enabling full disk encryption without using extremely long paraphrases. When a user buys a personal computer, the TPM is built into the computer's motherboard with the goal to offer security into the computer systems by generating the encryptions keys to protect the data in the drive. With the TPM in place, an attacker cannot remove the file from the systems or access the files elsewhere. Moreover, the TPM stores the encryption key that requires a user to login with a password to get access to the Windows and computer system.
The objective of this paper is to explore the concept the Trusted Platform Module, and the working protocol of the TMP technology.

Protecting Personal Data
Protection of personal data is paramount in any situation. Battered women receiving help in a shelter, part of a community clinic require confidentiality to avoid problems should their abusers locate them. When computerizing an appointment system and records, sometimes such information can easily be taken if there is no protection available. Things like passwords and encryption help keep would be criminals from accessing sensitive data. Although hackers may still access the data should they gain password information, adding those layers of protection, safeguard sensitive data on most occasions. While not all negative situations can be avoided, extra precaution must be taken when attempting to protect personal data.
The stakeholders of this scenario are several. The first and most important are the battered women and children in the shelter. They are the ones that may be endangered should their information leak out. The second are the staff working…… [Read More]

Strategy of E-Procurement and IT Architecture
1a) Planned Strategy in E-procurement
A large number of organizations adopting electronic commerce (e-commerce) have identified e-procurement as an effective strategy that can be used to enhance the competitive market advantages. In a business environment, a traditional procurement faces challenges of a paperwork workload associated that includes a purchase order, delivery order, and statement of work, invoice, and payment. All these process increase an organizational cost of production. Typically, e-procurement eliminates this workload by assisting management purchasing or supplying goods and services electronically at lowest possible costs using the paperless transactions.
A report carried out by the CIPS (2013) reveals that the goal of e-procurement is to use the latest information technology to link suppliers and customers thereby improve the value chain process. In essence, the e-procurement is a critical component of e-commerce, and the major goal of an e-procurement process is to enhance…… [Read More]
Privacy and Security: Apple vs. Federal Government
With increased usage of smartphones and other mobile devices, concerns over unauthorized access to private and confidential data stored in the devices have soared. In recent times, Apple Inc., one of the largest manufacturers of smartphones in the U.S. and worldwide, resorted to robust cryptographic techniques in an attempt to protect data customers store on its devices. The move has led to a fierce battle between Apple and the federal government, with the latter citing national security concerns. The government's concerns over national security have gained further momentum following the discovery that one of the masterminds of the December 2015 San Bernardino terrorist attack owned an iPhone 5C (Stavridis). Unable to unlock the device due to Apple's strong encryption software, the Federal Bureau of Investigations (FBI) sought the intervention of the courts to compel Apple, under the premise of All Writs of 1789,…… [Read More]
Certificates can be personal or set up by the users for certain trusted authorities. Once an SSL connection is recognized, the server certificate in use can usually be scrutinized by looking at the assets of the page conveyed over the SSL connection. Certificates and keys are normally stored on the hard disk of the computer. Additionally to needing a password when the private key is used, it is typically also required to import or export keys and certificates. Some browsers also hold key and certificate storage on a secure external device (Using PKI, 2004).
Certificates given to web servers and individuals are signed by a Certificate Authority. The signature on a certificate recognizes the particular Certificate Authority that issued a certificate. The Certificate Authority in turn has a certificate that connects its identity to its public key, so you can verify its uniqueness. A certificate authority issues a policy defining…… [Read More]

This translates into the use of system cache as part of the memory allocation algorithms inherent in the VA memory space approach to managing memory in Vista. In addition, memory manager now relies on kernel page tables that are loaded at system initiation and allocated on demand. This saves a significant amount of system resources including a minimum of 1.5MB on Intel x86-based systems and up to 3MB on PAE-based systems. The resource savings are exponential when applied to 64-bit systems, where up to 2.5GB of memory can be saved through this approach to memory management. Microsoft also continued this approach to the definition of the boot sequence on systems with large registries, predominantly found on 32-bit based Intel systems. The options on this specific Memory Managers include turning on or off the option of using a 3GB switch, which is essential for larger systems used for multipath network configurations.…… [Read More]
The self-encrypting hard drives technology enables the automatic encryption of every data written to the disk while restricting access to people without the correct password immediately the computer starts up. Furthermore, since the encryption is built in to the hard drive, it automatically encrypts and decrypts with no performance delay.
