Website Designing and Enhancements

Posted by arlene

If Web pages are the meat and potatoes of your site, interactive applications and other Web enhancements must be the gravy. Interactive Web applications add flavor and character to your site that you could never achieve with a typical static Web page. The proper design of interactive applications requires the skills of a seasoned Web [...]

Office Skype Peers? Block Skype in Workplace

Posted by arlene

From a security or network administrator’s point of view, the very same features that make Skype connect reliably through a restrictive firewall present a challenge to preventing or blocking Skype traffic on a network. Skype is very robust and can function with access to only port 80. Most corporations allow outbound Web traffic, so port [...]

Four Basic Modes of Cryptographic Public Keys

Posted by arlene

When the message to be encrypted is longer than the block length of the cipher, it is necessary to execute the algorithm several times and to combine the results in some way. The method of combination is called the mode of operation.
Electronic Codebook Mode
In electronic codebook (ECB) mode the encryption algorithm is applied independently to [...]

BITS Authentication

Posted by arlene

Even though BITS supports secure connections over HTTPS, you will most likely want to provide additional security. You can do this by specifically setting the credentials that BITS uses to access the files on the server. BITS supports Basic, Challenge/Response, and Passport authentication schemes.
To execute the sample application, you need to create a virtual directory [...]

The Skype API Operates on Windows and Mae OS X

Posted by arlene

The implementation of the API for Windows is such that messages are sent between the plug-in application and Skype by using the Win32 SendMessage() function. This standard mechanism for communication under the Windows operating system can be difficult to implement if you are not used to low-level Win32 communications.

The Skype API of Linux, SkypeNet and SkypeWeb

Posted by arlene

If you are running Fedora Core 3, SuSe 9, Mandriva 10.1 Debian, or Gentoo 1.4., you should not have any trouble using the Skype API. As previously mentioned, to write to the Skype API on Linux, you must have the D-BUS distributions. Once you have built the D- BUS components, you can update the /etc/dbus-1/system.d/skype.conf [...]

Processes of OS and NOS Hardening continue…

Posted by arlene

Updates
Updates for OSes and NOSes are provided by the manufacturer of the specific component. Updates contain improvements to the OS, and new or improved components that the manufacturer believes will make the product more stable, usable, secure, or otherwise attractive to end users. For example, Microsoft updates are often specifically labeled Security Updates. If you [...]

Network Hardening OSes and NOSes

Posted by arlene

When discussing network hardening, there are a number of concerns that are separate from those realized while evaluating and hardening OSes and NOSes. The appropriate firmware and OS updates implemented on hardware must be evaluated, tested, and implemented. In addition, network configurations must be as tight as possible. This includes developing appropriate rule sets and [...]

PKI (public key infrastructure) Management and Certificate Lifecycle

Posted by arlene

Certificates and keys, just like drivers’ licenses and credit cards, have a life cycle. Different factors play into the lifecycle of a particular key or certificate. Many things can happen to affect the usable life span of a key—they may become compromised or their certificates may be revoked or destroyed. Certificates also have an expiration [...]

Security of File Servers Consideration

Posted by arlene

Security with file servers usually consists of user identification procedures provided by password access to individual servers and individual file protection by user authorization for each file. These provisions can prevent accidental access but become inadequate to protect against willful unauthorized access or harm.
Advantages of File Servers
File servers provide a number of advantages over individual [...]

File Servers Hardware Network Data Requirements

File Servers Hardware

A file server system typically has the following components:
One or more computers with relatively large disk capacity, usually called servers.
Smaller computers, usually called work stations, at users’ desks.
Communications equipment.

The servers may use any type of operating system—for example, MS-DOS, Windows, Windows/NT, UNIX, or OS/2. If a server uses MS-DOS,the network software creates another [...]

Hybrid Routing Protocols

Posted by arlene

The use of hybrid routing is an approach that is often used to obtain a better balance between the adaptability to varying network conditions and the routing overhead. These protocols use a combination of reactive and proactive principles, each applied under different conditions, places, or regions. For instance, a hybrid routing protocol may benefit from [...]

Coded Data Cryptographic Systems Software

Posted by arlene

The aim of this is to outline the details of some commercial products which employ cryptographic techniques. Some of these products are packages, while others are software entities which provide infrastructural facilities for sending coded data and are often hidden deep in system software. This does not include details of SSL: that follows it treats [...]

Network and Programming: the .Net framework

Posted by arlene

In 2000, Microsoft announced what is probably its largest software development programme. It was known as .Net and involved configuring many of its products such as Excel, Word, MS Access together with its supported programming languages such as Visual Basic and C++ so that they are seamlessly integrated with the Internet and with each other.
