Protecting Against Intruders with Security- Firewall

As an administrator in today’s world of networked computing and easy access to the Internet, security both internally and externally must be the first and last issue considered. Denying unauthorized access is the first step to keeping your system secure. The mechanism to prevent access to all or some network services on a system is called a firewall.
Every operating system allows for the implementation of a firewall differently. Red Hat Enterprise Linux uses IPTables, a network packet-filtering mechanism in the Linux kernel. IPTables can be used to allow or deny packets based on numerous factors including their destination, their source, which port they are trying to access, the user ID of the process that created the packet, and more.
Install the iptables RPM package to use IPTables. It includes utilities to configure which packets to filter. The IPTables configuration consists of a series of rules. Each rule must be for a specific table, with each table having its own set of chains. A chain is a list of rules, which are compared to the packets passed through the chain. If a set of packets matches a chain, the target of the rule tells the system what to do with the packets, including passing it along to a different chain.
This section discusses how to write and enable IPTables rules. It also discusses the Red Hat Enterprise Linux security levels, which are predefined sets of IPTables rules. They can be used to quickly implement a basic firewall.

Protecting Against Intruders with Security- Enhanced Linux

On a system without Security-Enhanced Linux (SELinux) enabled, discretionary access control (DAC) is used for file security. Basic file permissions are used to grant file access to users. Users and programs alike are allowed to grant insecure file permissions to others. For users, there is no way for an administrator to prevent a user from granting world-readable and world writable permissions to his files. For programs, the file operations are performed as the owner of the process, which can be the root user, giving the program access to any file on the system.
SELinux is a mandatory access control (MAC) mechanism, implemented in the kernel. Programs protected by SELinux are only allowed access to parts of the filesystem they require to function properly, meaning that if a program intentionally or unintentionally tries to access or modify a file not necessary for it to function or a file not in a directory controlled by the program, file access is denied and the action is logged. The ability to protect files with SELinux is implemented in the kernel. Exactly what files and directories are protected and to what extent they are protected is defined by the SELinux policy. This section gives instructions on how to enable the SELinux protection mechanism, describes the SELinux policies available in Red Hat Enterprise Linux, tells you how to read the SELinux permissions of a file, shows how the SELinux Troubleshooting Tool alerts you of SELinux errors, and steps you through how to change the security context of files.
