Security Concerns and Cyber Terms Defined: Firewalls, Vulnerability Scans and Penetration Testing
Hikvision Cybersecurity Blogs Offer Tips and Insights to Improve Security, Reduce Concerns with Backdoors
Security concerns and cyber terms are outlined, with tips to improve security, in the Security magazine article, “Explained: Firewalls, Vulnerability Scans and Penetration Tests.”
The article provides in-depth information about these cybersecurity measures:
- Firewall: The first line of defense for a network that protects its various layers by permitting or denying traffic. Network segmentation is another preventive measure to ensure various departments are protected.
- Vulnerability Assessment: A preventive measure that attempts to uncover weaknesses and vulnerabilities within an organization’s network. “The scan targets the entire network identifying all devices, servers and endpoints by IP address. The scan will identify the applications and operating systems that are in use. Gathered data is cross-referenced against a security database for known exploits and vulnerabilities,” said the article. Once vulnerabilities are identified, the organization can begin updating and fixing these weaknesses.
- Penetration Testing: In this case, a specialist—often an ethical hacker—will be hired to try to breach an organization’s network to test vulnerabilities and exploits in software, operating systems or end user protections such as passwords.
To prevent and address security concerns, the article recommended that organizations identify security risks with an assessment of hardware and software platforms; develop and implement a remediation strategy to improve security controls; and develop a response plan and recovery process in the event of a cyberattack.
