Information security typically involves physical and digital security method to protect data from unauthorized access, vulnerability, replication or destruction. These methods can include mantraps, encryption key management, network intrusion detection systems, password policies and regulatory compliance. A security audit may be conducted to estimate the organization’s ability to maintain secure systems against a set of conventional criteria.
Threats to sensitive and personal information come in various forms, such as malware and phishing attacks, identity theft and ransomware. To prevent attackers and mitigate vulnerabilities at various points, multiple security controls are implemented and synchronized as part of a layered defense in depth strategy. This should minimize the risk of an attack. To be prepared for a security breach, security groups should have an incident response plan (IRP) in organisation. This security measures should allow them to limit the damage, eliminate the cause and apply updated defense controls.
