The best things in life are free and open source software is one of them. Security at data and network level is greatly enhanced by these software tools which open the door to a more safe and secure cyberworld.
Gnu PG: Guarding Your Privacy The GNU Privacy Guard/GPG is a tool which is used for file and email encryption. A strong encryption measure will provide immense security at the data level. This is a viable open source alternative to PGP or Pretty Good Privacy. It complies with OpenPGP standards. This is command line tool part of major Linux offerings such as Ubuntu, openSUSE, CentOS and Fedora. So, throw your hat in the ring today and use this amazing tool to protect data by using GPG to generate public and private keys in the 10 Open Source Software Cyber security Tools
VeraCrypt: A Real Solution Many open source utilities are there for disk level encryption. VeraCrypt is perfect for disk level encryption. This open source security tool is used for on the fly disk encryption. This handy tool is the correct choice because VeraCrypt encrypts automatically before data is saved on the disk and decrypts it completely after it is loaded from the disk sans user intervention.
Open Web Application Security Project: Combating Web Vulnerabilities Application security is as critical as other levels of security because just as web presence and development is increasing, web vulnerabilities are also rising. Application security is important. OWASP is an open source web app security project which provides best practices and code review steps among other guidelines which developers, architects and designers can use to develop secure software.
ClamAV: The Perfect Antivirus Tool Host level security offers protection for single devices such as servers PCs and laptops. ClamAV is the perfect antivirus system to scan data emanating from different sources. This is an open source antivirus designed for catching malware, viruses and deadly Trojans which attempt to steal information.
OSSEC: Integrating Security Needs Open Source SECurity is a open source tool that provides SIM and SEM solution as well as log monitoring. This is an open source HIDS or Home Based Intrusion Detection System. OSSEC helps customers to meet standards and integrate Security Incident Management and Security Event Management.
Snort: IDS/IPS Tool with a Difference Snort is an open source network IDS/IPS (Intrusion Detection and Prevention System) which performs detection and analysis of network traffic moving across in a more detailed way than an average firewall. IDS and IPS tools are known for analyzing traffic and comparing the packet to database of previous or known attack profiles. IDS tools alert IT staff regarding attacks, but IPS systems go a step further-they block harmful traffic. A blend of the two is an essential part of a comprehensive security architecture.
OpenVAS: Providing Comprehensive Vulnerability Scanning OpenVAS is a framework of services and tools offering intensive vulnerability scanning as well as management systems. It is the open source version of Nessus. 10 Open Source Software Cyber security Tools
Metasploit: The world’s most used penetration testing framework. Metasploit can test the security of different systems, including online-based or web-based applications, networks, servers, among others. Metasploit identifies all new security vulnerabilities as they emerge, thus ensuring round-the-clock security
KeePassXC: KeePassXC is a free and open-source password manager. It started as a community fork of KeePassX. Cybersecurity experts mostly use KeePass(XC) for identity management purposes.
Tor Browser: The Onion Router(TOR). The goal of onion routing was to have a way to use the internet with as much privacy as possible, and the idea was to route traffic through multiple servers and encrypt it each step of the way. This is still a simple explanation for how Tor works today.
