...Linux Security Technologies There are many ways to have internet access these days. Coffee shops, libraries, airports and even public buses have free wireless access. With all these free accesses to the World Wide Web, there is also many potential ways for hackers to potentially get your personal information and use it for their gain. There are many ways to combat this situation by using several security measures with Linux programming, which the majority of the software is free. Some of those security technologies are SELinux, TCP Wrappers, IPtables and Chroot Jail to name a few. SELinux is a security enhancement to Linux which allows users and administrators more control over access control. Access can be constrained on such variables as which users and applications can access which resources. Was developed by the NSA in December of 2000. These resources may take the form of files. Standard Linux access controls, such as file modes (-rwxr-xr-x) are modifiable by the user and the applications which the user runs. Conversely, SELinux access controls are determined by a policy loaded on the system which may not be changed by careless users or misbehaving applications. SELinux also adds finer granularity to access controls. Instead of only being able to specify who can read, write or execute a file, for example, SELinux lets you specify who can unlink, append only, move a file and so on. SELinux allows you to specify access to many resources other than files as well, such...
