Description: Hardened software refers to programs and operating systems that have been modified to reduce vulnerabilities and improve security. This process involves implementing various techniques and practices aimed at protecting the software against malicious attacks, exploits, and other cyber threats. Key characteristics of hardened software include the removal of unnecessary features, restriction of permissions, and the use of secure default configurations. Additionally, it focuses on minimizing the attack surface, meaning that opportunities for an attacker to exploit the system are reduced. The relevance of hardened software lies in its ability to protect sensitive data and maintain the integrity of systems, especially in environments where security is paramount. In a world where cyber threats are becoming increasingly sophisticated, software hardening becomes an essential practice for any organization looking to safeguard its technological infrastructure.
History: The concept of hardened software began to gain attention in the 1990s as organizations started to recognize the growing threat of cyber attacks. As operating systems and applications became more complex, so did the associated vulnerabilities. In 1999, the United States Department of Defense published the ‘Security Technical Implementation Guide’ (STIG), which provided guidelines for hardening software and systems. Since then, hardening has become a standard practice in the cybersecurity industry, evolving over time to adapt to new threats and technologies.
Uses: Hardened software is primarily used in environments where security is critical, such as in financial institutions, governments, and technology companies. It is applied in servers, workstations, and network devices to protect sensitive data and ensure business continuity. Additionally, it is used in software development to create more secure applications from inception, integrating hardening practices into the software development lifecycle (SDLC).
Examples: Examples of hardened software include operating systems and applications that have undergone modifications to enhance security. These may include server environments that remove unnecessary components to reduce the attack surface and those that offer secure default configurations. Specific applications that have been hardened can also be mentioned, such as databases that implement strict access controls and web servers that use advanced security configurations.
