Malware is a broad category encompassing various types of malicious software, including viruses, worms, and Trojans, designed to harm or exploit any programmable device or network. Malware can lead to data theft, damage, or unauthorized access to systems.
Types of Malware
Some common types of malware include:
- Viruses: Self-replicating programs that attach to legitimate files.
- Worms: Standalone software that spreads across networks.
- Trojans: Disguised as legitimate software to gain unauthorized access.
Insider Threats
Insider threats refer to risks that originate from within the organization. These can be employees, contractors, or business associates who misuse their access to sensitive information intentionally or unintentionally.
Addressing Insider Threats
To combat insider threats, organizations should:
- Implement strict access controls based on least privilege.
- Conduct regular training on data handling and cybersecurity policies.
- Monitor user activity for unusual behavior patterns.
The Evolving Landscape of Cybersecurity
