If this is your first experience with a SIEM, this one can get you started. Take the time to learn the ins and outs of the product and you'll most likely be satisfied with it if your company is an SMB. If you need compliance reports, OSSIM is too small for you, you'll need to go with USM or USM Anywhere.

Nessus is perfectly suitable for performing comprehensive vulnerability assessment scans being a vulnerability scanner. It is less appropriate for performing penetration testing since it is not a penetration testing tool, it does not have the ability and modules to exploit the vulnerabilities of the system.

Pros
AT&T Cybersecurity
  • Asset discovery. Once installed in a centric, network-accessible server, OSSIM can poll all your endpoints with common protocols (SSH, SNMP, WMI) to detect and discover site-wide assets to monitor. You only need to group them by your own criteria once added to the product.
  • SIEM Event Correlation. You can define quite complex correlation rules to detect possible suspicious or malicious actions or attempts in your network, in order to categorize them as real threats or as false positives, thus streamlining your risk assessment and management.
  • Ease of installation. The entire AlienVault OSSIM is self-contained in an ISO file, which can be burned into a DVD or just mounted in your server of choice (physical or virtual) for deployment. The installation process is automated and quote verbosed, with options for static IP, email messaging and others.
  • Ease of access. Being AlienVault OSSIM a self-contained appliance, it can be accessed via web by any device that supports a web browser, being that desktops, workstation, mobile devices, etc. The OSSIM dashboard and other features are automatically rearranged to adapt to the particular device being in use.

  • Nessus points out any vulnerable or outdated software Technologies used in the system, thus eliminating any chances for security flaws being turned up.
  • Nessus typically points any configuration level issues in accordance with the OWASP guidelines. Even the configuration of SSL related which are most of the time handled by some vendors or 3rd parties.
  • Nessus not only lists out these Vulnerabilities but describes clearly the vulnerabilities in details with its thousands of plugins updated regularly, the tool also recommends solution with practical details of easy implementation.

  • Could use an upgrade within reports.
  • Scans can take a long time to complete. Have to break them down in small sections.

Usability
AT&T Cybersecurity
AlienVault OSSIM is far easy to use and manage - provided you know what you're doing. As any SIEM application, there is some background knowledge required in order to take advantage of the product's functionalities, such as the log correlation and analysis. Other than that, the application is quite usable and robust.

It's very much a plug and play application that the user can go into with limited knowledge and set-up scans in minutes.

Everything is done through MSSP and installation pro services. Once those hours are burned up, then you're on your own without a lot of help. Typically the pro services hours aren't enough to get past 60 days and MSSP are hit and miss. We had a miss for installation helpers.

Originally my organization leveraged alien value due to the lower cost of entry and ability to manage it as a service provider. Unfortunately, after several years of working with this tool, it became unwieldy to use as it felt that almost every useful report had to be created by hand. As other tools have come out with the ability to do automated responses such as Stellar Data processor, we have begun to evaluate alternatives.

Sometimes when we identify a vulnerability with Nessus that has an exploit, we made a proof of concept with Metasploit in order to show to the IT managers the importance of the software/hardware hardening.

  • Nessus certainly has a positive impact while me while performing my job, either as security research, or performing vulnerability assessments for clients. It gives a lot of information about the system/application after performing scans. The number of false positives is also less compared to other vulnerability scanners.
  • The professional edition is very useful as policy templates available in this edition are very handy and useful even to perform compliance scan like PCI DSS scan.
  • Also, the ability to export the scan results into reports in formats like HTML, PDF is very useful which could be for performing system/application reviews.
