Kerio Control is able to log and block traffic from IP addresses of known intruders (so-called blacklists). Such method of detection and blocking of intruders is much faster and also less demanding than detection of the individual intrusion types. However, there are also disadvantages. Blacklists cannot include IP addresses of all possible intruders. Blacklists may also include IP addresses of legitimate clients or servers. Therefore, you can set the same actions for blacklists as for detected intrusions.
For correct functionality of the intrusion detection system, update databases of known intrusions and intruder IP addresses regularly.
Under normal circumstances there is no reason to disable automatic updates — non-updated databases decrease the effectiveness of the intrusion prevention system.
Here’s the thing about home security systems: they are expensive, usually require experts to install them, and for the good ones you’ll need to pay a monthly fee starting at $30 to have a company monitor them. While they won’t provide the same level of security as a professionally installed system from ADT or Slomin, the current wave of smart home cameras released by companies such as Nest, Logitech, and even Amazon have made security systems cheaper and easier to install and monitor from your smartphone. And the camera that still leads the pack in terms of ease of use is Netgear’s Arlo.
The newest addition to the lineup is the Arlo Pro 2, its latest wireless camera that works both indoors and outdoors. Before we even get into the details, the Arlo Pro 2 already checks the three main boxes — no wires, 1080p HD stream, and weatherproof — that you’d be hard-pressed to find in any other security camera. It also features free cloud storage for a week, two-way audio, a rechargeable battery that lasts six months, and a 130-degree field of view.
Setting up the Arlo Pro 2 system is simple. The camera system is sold with two cameras and a base station that plugs into your router to manage the connections. (You can plug in an external hard drive to the base station to back up your recordings locally.) Once you sync the camera with the base station, you can easily mount the camera on any wall with a screwdriver and the included magnetized mount in about five minutes. The included mounts keep the camera close to the wall, but you can buy extended mounts (great for mounting it on the side of your house or on a tree outdoors) for $19.
Intrusion prevention system overview
Kerio Control integrates Snort, an intrusion detection and prevention system protecting the firewall and the local network from known network intrusions.
A network intrusion is network traffic that impacts the functionality or security of the victim-host. A typical attribute of intrusions is their apparent legitimacy and it is difficult to uncover such traffic and filter it simply by traffic rules. Let us use Denial of Service intrusion as an example — too many connections are established on a port to use up the system resources of the server application so that no other users can connect. However, the firewall considers this act only as access to an allowed port.
