In today’s ever-evolving cybersecurity landscape, networks face a constant barrage of threats from malicious actors who actively seek out vulnerabilities to exploit. As a result, network hardening has become a critical practice that organizations must diligently undertake to fortify their defenses and eliminate potential security weaknesses. While it is impossible to achieve complete immunity to attacks, implementing robust network hardening measures can significantly reduce the likelihood of successful data breaches and mitigate potential damages.
Network hardening refers to the configuration of systems to minimize vulnerabilities and reduce the risk of cybercrime. Cyber attacks have evolved to become more covert and targeted. So, your network services and systems need reinforcement to become more resilient to attacks. Cybersecurity hardening secures networks from external security threats and internal vulnerabilities. It first identifies security vulnerabilities such as access, programs, outdated network devices, default passwords, and unencrypted data, and like a door left wide open, it closes them.
Network hardening techniques that once involved blocking unauthorized network access have since become outdated, as they only focused on firewalls. Modern attacks bypass perimeters because of the increased remote access by employees and third-party access.
By automating network operations, administrators can enhance network device hardening by disabling unused ports and services, installing software updates and security patches, implementing strong access controls, enforcing secure firewall configurations, and monitoring network traffic for malicious activities.
Operating system hardening strengthens network defenses and keeps the systems resilient by making it harder for hackers to gain unauthorized network access or move laterally within the network once they have breached perimeter security controls.
Network hardening is essential for protecting organizational assets from cyber threats and data breaches. The frequency and complexity of cybercrime have seen financial firms lose around USD 12 billion in the last twenty years, threatening global financial stability.
Hardening network security helps keep your networks safe from external and internal attacks. Hackers constantly probe networks for weak points like open ports and unpatched systems. With more sensitive data leaving the office to remote places and the over-reliance on cloud storage, network hardening should be a primary focus.
Access to data on business networks results in compromises that could lead to reputational damage, financial losses, and legal liability. Hardening strengthens network defenses to mitigate risks, meet compliance needs, and help ensure network operations run without security incidents.
On top of safeguarding an organization’s network against malicious attacks, server hardening has additional benefits. A network hardening checklist helps improve performance and security as hackers can exploit fewer exposed weaknesses. Hardening also streamlines auditing and compliance tasks by reducing the number of programs.
With a hardened system, there are fewer chances of potential entry points for hackers, strengthening the entire network and enhancing your organization’s security posture.
The hardening network process comprises three key phases, each serving unique objectives and presenting distinct challenges. Let’s delve into each phase to gain a comprehensive understanding of the network hardening process and its significance in ensuring network security:
The second phase of network hardening involves identifying and addressing security vulnerabilities. Traditionally, this process relied on manual analysis or custom scripts, both of which had limitations. Manual analysis was time-consuming and prone to errors, while custom scripts lacked portability and were challenging to maintain.Leveraging automation tools, such as NetBrain’s NextGen network visualization tools, simplifies and accelerates the process, enabling proactive enforcement of security measures and ensuring a resilient network infrastructure.
Embrace the power of network hardening strategies, like automation, to safeguard your network from potential threats and mitigate the risks associated with today’s dynamic threat landscape.
