In IT, hardening helps limit the threat of attack by turning off non-essential services and patching vulnerabilities. It essentially locks down a system, making it harder for attackers to breach security by removing anything other than the basic configurations necessary to run.

Threats to consider

Hardening typically minimizes the risks of misconfigurations and operational problems. It also simplifies the compliance process and helps guard against security issues. When looking at the hardening process, it鈥檚 essential to consider all possible security threats to know what you鈥檙e protecting against and how best to do it. These include the following:

• Malware distribution

• Identity theft

• Sabotaging processes

• Manipulating applications

• Data leakage through hacking

What does hardening mean in software development?

During the software development life cycle (SDLC), hardening refers to applying security strategies while creating new software to reduce avenues for an attack. Coding languages can be susceptible to vulnerabilities, so software developers must thoroughly understand this to ensure the new application is secure. Establishing a secure software development policy can help your organization with this issue.

Hardening examples

To protect against these threats and others, you can choose from a number of hardening options, depending on your organization. Hardening can never be 100 percent attack-proof, but you can look for various industry benchmarks. Several different types of hardening exist, including:

• Server

• Software application

• Operating system

• Database

• Network hardening

Some hardening measures include these:

Automating updates: Software and hardware updates and patches are necessary for all businesses. Automating them eliminates any human error resulting in a delay in updates, meaning at no time will your system or network remain unprotected.听

Scanning regularly: To increase security, monitor and scan systems regularly for any vulnerabilities, weaknesses, or viruses. You can also automate this process.

Training staff: It is effective to train all staff members on security threats and how to protect systems from attacks. This might include how to look out for phishing and how to transfer data safely.

Managing passwords: A weak password can mean the infiltration of a whole system or network, so it is essential that all users reset their passwords if the company suspects a breach of security. The users should also utilize processes like password rotation.

Documenting processes: Being aware of what鈥檚 going on is vital, so documenting a threat or unusual occurrence means that others know if it has happened before when they encounter it. This helps with troubleshooting and identifying threats.
