Tools to protect your system from attackers

There are lots of tools available in the market to help individuals or network administrators secure their systems. Some tools are free, while others are paid and some are open source.

KeePass

KeePass is free and open source software to manage all your passwords in one place, securely. Sometimes we use the same passwords for different accounts on different websites, which could lead to a serious problem. If someone cracks that password and has your user ID, then they will have access to your different accounts. Sometimes we also store passwords in browsers, which is also not a safe habit, as anyone getting access to your computer can see them. KeePass provides the best solution.

Different passwords can be managed in one place with just one master password with an encrypted layer. All the passwords are unlocked by this master key and, at the backend, all the passwords are stored in a highly encrypted format by using the most popular and uncrackable algorithms. You can give it a try if you are tired of trying to remember passwords and want to store them securely.




Kali Linux

This is an offensive Debian based Linux security distribution with lots of free software, utilities and security testing tools. It’s widely used for penetration testing. If you want to be a hacker, you should learn Kali OS.

Nikto

This free and open source Web server scanner comes with comprehensive test scenarios covering thousands of vulnerabilities. Though it cannot detect all kinds of exploits (SQL based exploits), this tool is still very handy to check for popular vulnerabilities missed in the Web server. It also checks for outdated versions and misconfigurations related to server settings. It has been in the market for almost 10 years.

Security Onion

This is a defensive Debian based Linux security distribution for network security monitoring. It is used for intrusion detection and for log management purposes. It acts like an army commander and contains different tools like Snort, OSSEC, Squert, NetworkMiner, ELSA, etc, for defence.

Nmap

Nmap (Network Mapper) is a free and open source utility for network discovery and audit. It is used to map your network and ports. It also has scripts that can detect network related issues. Nmap fetches raw data and determines the host type, OS type and hosts available in the network.

OSSEC

This is a free and open source host-based intrusion detection system (HIDS), which is very easy to set up and use. It can provide security alerts that even we can write scripts for, to serve different purposes. We can add more capabilities by tweaking the source code.
