Snort

Cisco

Snort is the foremost Open Source Intrusion Prevention System (IPS) in the world. Snort IPS uses a series of rules that help define malicious network activity and uses those rules to find packets that match against them and generates alerts for users. Snort can be deployed inline to stop these packets, as well. Snort has three primary uses: As a packet sniffer like tcpdump, as a packet logger — which is useful for network traffic debugging, or it can be used as a full-blown network intrusion prevention system. Snort can be downloaded and configured for personal and business use alike. Once downloaded and configured, Snort rules are distributed in two sets: The “Community Ruleset” and the “Snort Subscriber Ruleset.” The Snort Subscriber Ruleset is developed, tested, and approved by Cisco Talos. Subscribers to the Snort Subscriber Ruleset will receive the ruleset in real-time as they are released to Cisco customers.

ACSIA

DKSU4Securitas Ltd

ACSIA it is a ‘post-perimeter’ security tool which complements a traditional perimeter security model. It resides at the Application or Data layer. It monitors and protects the the platforms (physical/ VM/ Cloud/ Container platforms) where the data is stored which are the ultimate target of every attacker. Most companies secure their enterprise to ward off cyber adversaries by using perimeter defenses and blocking known adversary indicators of compromise (IOC). Adversary pre-compromise activities are largely executed outside the enterprise’s field of view, making them more difficult to detect. ACSIA is focused on stopping cyber threats at the pre attack phase. It is a hybrid product incorporating a SIEM (Security Incident and Event Management), Intrusion Detection Systems (IDS) Intrusion Prevention Systems (IPS), Firewall and much more. - Built for linux environments - Also monitors Windows servers - Kernel Level monitoring - Internal Threat detection

OPNsense

Simple packet filters are becoming a thing of the past. Even the open-source domain is moving towards Next-Generation Firewalls. And OPNsense is a top player when it comes to intrusion detection, application control, web filtering, and anti-virus. No network is too insignificant to be spared by an attacker. Even home networks, washing machines, and smartwatches are threatened and require a secure environment. Firewalls are a component of the security concept. They protect against known and new threats to computers and networks. A firewall offers the highest level of protection if its functions are known, its operation is simple, and it is ideally positioned in the surrounding infrastructure. OPNsense accepts the challenge and meets these criteria in different ways. This book is the ideal companion for understanding, installing and setting up an OPNsense firewall.
