Next-Generation Firewalls (NGFWs) and Intrusion Prevention Systems (IPS)

Assignment

Comprehensive Tools to Protect the Network Infrastructure Perimeter

Ensuring information security is an integral part of business processes, regardless of the company’s area of activity and scope. These days, information security should be given fundamental importance in any company. Modern network attacks are becoming increasingly complex, which requires comprehensive tools to protect the perimeter of network infrastructure.

Ensuring Protection Against Unauthorized External Access to Information Resources

The presence of a firewall is the minimum required to ensure protection against attacks and unauthorized external access attempts to information resources. Next-generation firewalls (NGFWs) not only provide classical traffic filtering but also offer intrusion protection (IPS) at all levels, including the application layer, as well as flow antivirus filtering, botnet protection, and traffic inspection functionality.

Establishing Comprehensive Protection for the Company's Network Infrastructure Perimeter

Network Rules as a Single Endpoint for Information Security Policies

Protection of Internet Access with the Ability to Flexibly Configure Traffic Filtering Policies and Rules

Organization of Secure Remote Access to the Organization's Corporate Resources

Organization of Secure Communication Channels with the Organization's Remote Branches

Monitoring Incoming and Outgoing Network Traffic and Resolving Blind Spots in the Network by

Decrypting SSL Traffic Based on a Defined Set of Security Rules**

Subsystem Composition

Almost all modern next-generation firewalls (NGFW) carry the functionality of the following subsystems:

01;Intrusion Prevention Subsystem;Its purpose is to detect attacks on the company's network in real time. In addition to having an up-to-date database of known attack signatures, an intrusion prevention system designed according to best practices can detect and eliminate even previously unknown types of attacks by examining the "normal behavior" of traffic.; 02;Antivirus Subsystem;Classic antivirus protection for endpoint workstations may not be sufficient to prevent infections. NGFW provides not only signature analysis of all traffic passing through it, but also behavioral analysis of transmitted files. A separate functionality is the ability to automatically transfer files to isolated environments (protected zones) for deep analysis.; 03;URL Filtering Subsystem;Illegitimate sites, combined with social engineering, are commonly used to steal user credentials, leading to the theft of both financial assets and sensitive data from an organization. The URL filtering subsystem regularly updates its databases by checking against non-legitimate sites and analyzing them for potential malicious code.; 04;Application Control Subsystem;Unfortunately, not all software developers pay the necessary attention to security. Application vulnerabilities are commonly exploited by attackers to carry out network attacks. The Application Control Subsystem contains information about relevant application vulnerabilities and prevents attacks targeting this threat vector.; 05;Remote Access Organization Subsystem;The current needs of businesses show that it is essential for employees to access the company’s resources from anywhere in the world. The NGFW’s task is to provide secure remote access by establishing a secure channel from the workstation to the company’s perimeter over the "Internet" network or by enabling access from any device via a web portal. NGFW also enables secure information exchange with remote branches, except for the potential loss of data transmitted via unreliable communication channels.;
