Programming Security Policy (part 4) - Programming Application Domain Policy
Application domain policy is the final layer of security policy evaluated when determining the code-access permissions to grant an assembly. Regardless of the permissions granted to an assembly based on the enterprise, machine, and user policies, you can further lock down its permissions using application domain policy.
Programming Security Policy (part 3) - Programming the Security Manager
The System.Security.SecurityManager class contains a set of static members that provide access to critical security system functionality and data. Most members of SecurityManager require the caller to have the ControlPolicy permission; ControlPolicy is an element of System.Security.Permissions.SecurityPermission.

Ethernet cables trailing across the floor simply isn't feasible in some homes, particularly if you live in shared accommodation and don't have access to the router directly. In this kind of property, wireless technology is the only feasible option.
Network Attached Storage Round-Up (Part 3) - Novice User, Feature Rich Single Disk NAS
Although setting up most NAS boxes is not difficult, k it still requires a degree of knowledge and technical acumen. Manufacturer Dane Elec has identified the need for a truly plug-and-play NAS box and has satisfied that demand with its MyDitto products.
Network Attached Storage Round-Up (Part 2) - Limitations Of NAS, NAS Noise And Power
In larger networks with a high volume of simultaneous I/O requests, a typical affordable NAS box is not going to be able to provide adequate performance. Their built-in CPUs will be too limited in performance and if over stretched will slow to a crawl.
Network Attached Storage Round-Up (Part 1) - The Benefits Of A NAS
In a small network with only a few PCs, having a domain-based network is needlessly expensive, because a workgroup with an attached NAS can afford the business much the same functionality at a greatly reduced price.
Which is the right router for you? (Part 3)
Each of the routers we've mentioned in this article have cable router analogues. If you're a cable broadband customer, simply look at the manufacturer's website to see what the cable equivalent is. You can expect prices to be similar, even though the model you will need lacks an internal ADSL modem.
Which is the right router for you? (Part 2) - Budget Routers
If investing in a new router, you should also insist on one with 802.11n wireless. An older model with 802.11g may save you a few pounds but puts you behind the times before you even start.
Which is the right router for you? (Part 1)

Most enthusiasts have at least one desktop and one laptop, but with the rising popularity of machines acting as media centres, it isn't uncommon to see homes with even more machines.
The key to security
To create a hardware lock for your PC, you first need to find yourself an old thumbdrive, preferably one that’s too small to be of any further practical use. You don’t need masses of space, so if you’ve got an 8GB one hanging around, hang onto it and dig into your junk drawer for an old 64MB one instead.
Netgear DGND3700 - The Ultimate Home Gateway
The reason for this, as determined by Netgear’s excellent technical support, turned out to be a conflict relating to my IE9 setup on that system. Switching to my laptop running the same browser allowed me to run the automatic wizard feature to set up the Netgear modem router.
Cisco Linksys X3000 - The Link to Connectivity
Cisco's Linksys X3000 modem router sits itself among the higher-end, slightly more premium range of devices -- and prices just similarly. Being up at the top means you're usually having a lot to offer, which means there's a lot for us to expect from the X3000 as well.
Protect your passwords (Part 3)
The most immediate way to use usernames and passwords saved in the KeePass database is to click on one, then click its URL in the lower pane of the user interface to bring up the relevant login page, and finally drag and drop the username and password into the input fields of the website.
Protect your passwords (Part 2) - KeePass
More importantly, it's open source. Where your passwords are concerned, this is a good idea because it means that anyone can inspect the source code, compile their own executable and be sure that no keylogger or malware is lurking and skimming off their credentials.
Protect your passwords (Part 1)
Analysis of cracked passwords has revealed that some are more popular than others. Believe it or not, ‘123456' is the world's most popular password, followed by 'password' and the username. In July 2011, Hotmail actually banned the password ‘123456'.
Mobile Viruses the risk keeps growing (Part 2) - iOS Apps in the Sandbox & Check App Authorisations
Apple’s method of isolation provides a measure of security: iOS only identifies the ‘root’ and ‘mobile’ user levels. Apps in a sandbox run on the ‘mobile’ level with limited rights: they may neither access other apps, nor change the kernel or start privileged processes that can’t be ended by iOS at any point to clear out memory.
Mobile Viruses the risk keeps growing (Part 1)
Mobile malware writers celebrated their first huge success in March this year: security experts found more than 50 unsafe apps in the Android market, which had infected about 200,000 devices within a few days.
Firewalls: Protection or Deception?
A firewall basically shuts down almost all the ports, in order to prevent unwanted packets from getting into the PC. The data packets can only use the ports that have been explicitly approved. So something like the most well known port (80), which carries all HTTP packets, must be open for the browser, otherwise you won’t be able to surf at all – and this is exactly where the firewall’s biggest problem lies.
Encrypt Your Entire Hard Drive with FileVault
If you're seriously concerned about privacy or you work with a lot of confidential files on your Mac, you might want to consider using FileVault. FileVault encrypts your entire hard drive, allowing file access only to users with the right password or access key.
