Network Security
In cybersecurity, "network security" refers to safeguards to ensure computer networks' availability, confidentiality, integrity, and the data they carry. The process entails employing many technologies, protocols, and guidelines to safeguard the software programs and hardware components that make up a network.
Critical goals of network security include:
Confidentiality: ensuring sensitive information can only be accessed by authorized people or systems. Data must be encrypted to guard against unwanted access.
Integrity: Guaranteeing the accuracy and reliability of data by protecting it from unauthorized modification. It can be achieved through measures like data integrity checks and digital signatures.
Availability: Ensuring that network resources and services are consistently accessible and usable. Measures such as redundancy, load balancing, and disaster recovery planning contribute to availability.
Authentication: Verifying the identity of users, devices, or systems before granting access to network resources. It often involves using passwords, multi-factor authentication, and digital certificates.
Authorization: Controlling access to specific resources based on the authenticated identity and associated permissions. It ensures that users or systems can only access the information or services for which they have permission.
Firewall Protection: Put firewalls in place to monitor and regulate incoming and outgoing network traffic by preset security regulations. A firewall keeps a trustworthy internal network isolated from an untrusted external network, such as the Internet.
Intrusion Detection and Prevention Systems (IDPS): putting in place measures to monitor system and network activity for any suspicious activity or infringements on security policies. Real-time threat detection and response are capabilities of IDPS.
Virtual Private Networks (VPNs): Remote users can connect to a private network as if they were physically, thereby establishing secure, encrypted connections via the Internet.
Security Auditing and Monitoring: Regularly reviewing and analyzing network logs and activities to detect and respond to security incidents. Auditing helps identify vulnerabilities and assess the effectiveness of security measures.
Patch Management: updating network devices, operating systems, and software with the newest security patches to fix known vulnerabilities and lower the chance of exploitation.
A comprehensive and tiered approach is necessary for adequate network security because no one solution can guarantee complete protection. To build a strong defense against cyber dangers, it combines software and hardware solutions with user awareness and education.
The ThreatNG all-in-one solution integrates External Attack Surface Management (EASM), Digital Risk Protection (DRP), and Security Ratings to fortify an organization's network security. Meticulously scanning and monitoring the external digital presence offers a comprehensive view of potential vulnerabilities, emerging threats, and digital risks. This solution complements network security measures by providing actionable insights into external threats and vulnerabilities, facilitating a seamless handoff of critical information. For instance, ThreatNG can identify unsecured assets in the external attack surface, and this intelligence seamlessly integrates with existing firewall policies and intrusion detection systems to enhance proactive threat mitigation. The Security Ratings aspect also helps organizations assess and improve their overall security posture, offering a continuous feedback loop for refining and strengthening existing network security protocols.
