Protect your network from viruses, malware and malicious activity with Kerio Control, the easy-to-administer yet powerful all-in-one security solution.

Kerio Control brings together next-generation firewall capabilities — including a network firewall and router, intrusion detection and prevention (IPS), gateway anti-virus, VPN, and web content and application filtering. These comprehensive capabilities and unmatched deployment flexibility make Kerio Control the ideal choice for small and mid-sized businesses.

Next-Generation Firewall, Router and Leading-Edge IPS

Preserve the integrity of your servers with deep packet inspection and advanced network routing capabilities — including simultaneous IPv4 and IPv6 support. Create inbound and outbound traffic policies, restricting communication by specific URL, application, traffic type, content category and time of day.

Kerio Control’s IPS adds a transparent layer of network protection, with Snort-based behavior analysis, and a regularly updated database of rules and blacklisted IP addresses from Emerging Threats.

Advanced Gateway Antivirus

Keep viruses, worms, trojans and spyware from infesting your network with integrated Kerio Antivirus.

The optional antivirus service scans all web and FTP traffic, email attachments and downloads, automatically updating itself with the latest virus definitions.

Industry-Leading Web, Content and Application Filtering

Selectively block, allow or log access to 141 categories of web content and applications using Kerio Control Web Filter with application awareness. Keep bandwidth-hogging traffic like streaming video off your network or block peer-to-peer networks. Keep your users from visiting malware sites that are known to contain viruses and spyware or to engage in phishing or identity theft.

The optional Kerio Control Web Filter with application awareness limits legal liability, protects your network and boosts user productivity by limiting user access to dangerous or inappropriate sites or those that just plain waste time.

Unmatched Quality of Service

Easily prioritize and monitor network traffic to guarantee high-speed transmission for the most important traffic types. Internet Link Load Balancing optimizes Internet access by distributing traffic across multiple links. Kerio Control monitors link availability, and automatically disables or re-enables links to ensure continuous Internet access.

Deploy as a software appliance, a virtual machine, or a performance-optimized hardware appliance. Remote deployment of hardware appliances is easier and faster than ever before with self-provisioning through MyKerio .

Kerio Control supports your organization’s IPv6 strategy, whether you’re transitioning from IPv4 or use both protocols. And you can use your favorite SNMP tools to monitor Kerio Control’s status.

Case Study: McDonald’s

“Until 1995, McDonald’s was not concerned with the information technology in its Czech and Slovakian outlets. But the need for operational efficiencies and visibility into what was happening locally drove the need for integrating IT into its business structure and centralizing its management,” says Václav Valenta, McDonald’s IT manager for the Czech and Slovak Republics. Valenta led the team that designed and built the company’s Information and Communication Technology (ICT) infrastructure.

    How to Easily Bypass Most Firewalls #bypass #firewall #for #facebook


    How to Easily Bypass Most Firewalls

    by eHow Internet Editor

    Many businesses set up firewalls to prevent their employees from visiting certain websites like Myspace or Facebook during work hours. In the past this was a difficult thing to do for anyone but advanced computer users. Thankfully there are programs and websites that can help beginners easily bypass these firewalls without any problem at all so that you can chat, send instant messages or go web surfing without being detected.

    Download HTTP Tunnel Client which is a software that makes it easy to bypass most firewalls. All of the communications for the network comes encrypted in the program and you don’t need to have a computer at home that you have to leave on all day to use it. This program works just as well as more advanced techniques without the hassle of setting everything up yourself.

    Sign up at Relakks, which is another easy way to bypass firewalls while at work or school. This site gives you a safe and encrypted connection between whatever computer you want to use and the Internet. Set up is easy. Just go to your “Start Menu,” “Control Panel,” “Network and Internet Connections.” From there select “Virtual Private Network connection” (VPN) and click next. Type “Relakks” in the box as the company name and then type “” as your “Host name or IP address,” and then click next. Then select “My Use Only,” if you don’t want anyone else to use this and click next to finish.

    Use Ghostzilla as your browser to prevent others from seeing what you are doing online. Ghostzilla works just the same as other browsers except that it shows up and then disappears quickly and hides behind whatever other applications or websites you are using. Just move your mouse and it quickly pops up to whatever page you want others to see.

    Cisco ASA and PIX Firewall Logging

    Chapter Description

    Cisco firewalls and security appliances can be configured to generate an audit trail of messages describing their activities. Firewall logs can be collected and analyzed to determine what types of traffic have been permitted or denied, what users have accessed various resources, and so on. This chapter presents the tasks that are necessary to begin generating and collecting logging messages.

    From the Book

    For more information on Security, visit our Security Reference Guide or sign up for our Security Newsletter

    Refer to the following sections for information about these topics:

    • 9-1: Managing the Firewall Clock Discusses ways to set and maintain the firewall s internal clock so that events and messages can have accurate time stamps.
    • 9-2: Generating Logging Messages Explains how firewalls generate logging messages and how you can configure them to do that.
    • 9-3: Fine-Tuning Logging Message Generation Covers the configuration steps that can be used to enable or disable specific logging messages or change their severity levels. This section also discusses how to configure access list activity logging.
    • 9-4: Analyzing Firewall Logs Provides an overview of how you can approach collecting and analyzing the logging messages that firewalls produce.

    Cisco firewalls and security appliances can be configured to generate an audit trail of messages describing their activities. Firewall logs can be collected and analyzed to determine what types of traffic have been permitted or denied, what users have accessed various resources, and so on.

    This chapter presents the tasks that are necessary to begin generating and collecting logging messages.

    9-1: Managing the Firewall Clock

    A Cisco firewall keeps an internal clock that can be used for Syslog time stamps, certificate time stamps, and so on. The clock is powered by a battery in the absence of regular power.

    The internal clock is always based on Coordinated Universal Time (UTC). UTC was previously known as Greenwich Mean Time (GMT).

    You can set the system time using two different approaches:

    • Manually You set the time and date on the firewall along with the time zone and specify whether to observe daylight savings time. With manual configuration, the firewall clock is only as accurate as the internal clock hardware.
    • Using Network Time Protocol (NTP) This is a protocol defined by RFC 1305 that provides a mechanism for the devices in the network to get their time from an NTP server. With NTP, all the devices are synchronized to a common, trusted source and keep very accurate time.

    NTP uses the concept of stratum to determine how close an NTP server is to an authoritative time source (an atomic or radio clock). Stratum 1 means that an NTP server is directly connected to an authoritative time source. NTP also compares the times reported from all configured NTP peers and does not listen to a peer that has a significantly different time.

    NTP associations with other NTP peers can be protected through an encrypted authentication.

    NTP version 3 is based on RFC 1305 and uses UDP port 123. Information about public NTP servers and other NTP subjects can be found at .

    You can also use a commercial product as your own stratum 1 time source. For example, Symmetricom ( ) offers several NTP time servers that are based on Global Positioning Satellite (GPS) signals.

    Setting the Clock Manually

    1. (Optional) Identify the time zone:

    Firewall(config)# clock timezonezone-name hours [minutes ]

    zone-name is the time zone (an arbitrary text string such as EST) and is hours (0 to 12 or 0 to 12) and optionally minutes offset from UTC. For example, Eastern Standard Time in the U.S. is 5 hours behind UTC and would be configured as follows:

    Firewall(config)# clock timezone EST -5

  • (Optional) Set daylight savings time (summer time) parameters.
    1. Use the following command if daylight savings time recurs at regular intervals:

    If daylight savings time begins and ends on a certain day and week of a month, you can use this command. The name of the daylight savings time zone is given as zone (an arbitrary name or abbreviation, such as EDT). The week number week (1 to 4 or the words first and last ), the name of the weekday. the name of the month (only the first three letters matter), and the time hh:mm in 24-hour format can all be given to start and stop daylight savings time. The offset value gives the number of minutes to add during daylight savings time (the default is 60 minutes).

    For example, daylight savings time in the U.S. begins at 2 a.m. on the first Sunday in April and ends at 2 a.m. on the last Sunday in October. You could define it with this command:

    You can use the recurring keyword with no other arguments for any of the U.S. and Canadian time zones. The correct begin and end dates are used automatically. For the preceding example, you could define daylight savings time as follows:

    Firewall(config)# clock summer-time EDT recurring

  • If daylight savings time occurs at specific times, you can use the following command to specify the exact date and time that daylight savings time begins and ends in a given year:

    This command is useful if the begin and end times change from year to year. Specify the year number as year (four digits, 1993 to 2035).

  • Set the firewall clock:

    The clock is set when this command is executed. The time is given in 24-hour format, day is the day number (1 to 31), month is the name of the month (only the first three letters are needed), and year is the full four-digit year. The day and month parameters can be reversed, according to what is customary.

  • Verify the clock:

    The current time and date are shown. If you use the detail keyword, the source of the time ( hardware calendar is the internal battery-operated clock) and any daylight savings time definitions are shown, as in this example:

    Setting the Clock with NTP

    In PIX 7.x multiple-context mode, NTP must be configured on the system execution space only. All the other contexts (both admin and user) obtain their clock information from the system execution space, because all the contexts exist in the same physical firewall. You can use the changeto system command to move your session into the system execution space before using the following configuration steps.

    The Firewall Services Module (FWSM) doesn t have a standalone clock, and it doesn t support NTP. Because it is a module inside a Catalyst 6500 chassis, it relies on the switch clock instead. Therefore, you should make sure the switch has been configured for NTP as an accurate clock source.

    1. (Optional) Use NTP authentication./p>
      1. Define an authentication key:

      An MD5 authentication key numbered key-number (1 to 4294967295) is created. The key is given a text-string value of up to eight cleartext characters. After the configuration is written to Flash memory, the key value is displayed in its encrypted form.

      You can repeat this command to define additional keys if needed.

    2. (Optional) Identify a key to expect from all defined NTP servers:

      Remote NTP peers must authenticate themselves with the firewall using the authentication key numbered key-number (1 to 4294967295), as defined in Step 1a. If this command is used, any NTP server must supply this key to the firewall before its time update information is accepted. You can repeat this command to identify additional keys to expect. (Trusted keys can also be defined on a per-server basis in Step 2.)

    3. Enable NTP authentication:
  • Specify an NTP server:

    The NTP peer (server) is identified at ip-address. If you are using NTP authentication, you can use the key keyword to identify which authentication key to expect from this server. (See Step 1a.) By default, the firewall sends NTP packets on the interface derived from its routing table. You can specify an interface to use with the source keyword and the interface named if-name (outside or inside. for example).

    You can repeat this command to define more than one NTP server. If one server is down or unavailable, a second or third server could be used to synchronize time. You can use the prefer keyword to indicate one NTP server that is preferred if multiple NTP servers are configured.

    Actually, a firewall using NTP can use its associations with several servers to derive a more accurate idea of the time. If possible, you should configure a minimum of three different NTP servers so that your firewall can determine if any one of them is inaccurate.

  • Verify NTP operation.
    1. Verify the NTP configuration commands:
