All computer networks – private and business – must have a security system. On a personal level, this can include effective firewalls, up-to-date systems, and technical and physical data stores, but organizations may need to have a network security policy in place to follow industry best practices. Best practices for several departments require organizations to create network security policies that include risk assessment and management and include regular IT audits to update systems against new attack tactics.
Network security standards cover all the ways organizations need data: ease of use, reliability, integrity, and security. To protect this data, anti-virus and anti-spyware programs, firewalls, intrusion prevention systems (IPS), and express virtual private networks (written as 익스프레스 가상 사설망 in the Korean language) can be added to corporate systems in any combination, and all of them must be regularly updated and maintained.

For businesses or organizations that use credit cards or electronic information management systems, privacy is beyond convenience, and in the event of a breach of security, business, money, fraud, identity theft, legal process, stolen records, or corrupted information may result.
However, hackers and similar online criminals are constantly rethinking their tactics to bypass or bypass firewalls, and networks need to be updated to deal with new threats. While the threats are many, they usually fall into the following categories:
- Viruses and worms
- Trojans
- Spam
- Phishing
- Packet snapping
Network assessments can find points where threats can enter and suggest solutions to address them. Network security assessment firms use a combination of ethical hacking techniques – imitating external threats to identify vulnerabilities – and social engineering to uncover those weaker areas. Assessments typically cover technical, physical, and personal areas through penetration testing, employee assessments, vulnerability scanning, research into operating system settings, and analysis of previous attacks. The result is a report that explains all the weak points and provides solutions.
