Because there are just too many.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Larry Grossman, acting chief information security officer (CISO) at the Federal Aviation Administration, said he has a team looking at how to reduce the number of tools. Grossman was speaking Oct. 1 at the Northern Virginia Technology Council\u2019s Cybersecurity Summit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Across the federal government, agencies have so many security tools deployed on their networks that they may not know the exact number. Several agencies don\u2019t know what tools even sit on their networks, according to <a href=\"https:\/\/www.nextgov.com\/cybersecurity\/2019\/06\/agencies-are-leaving-sensitive-data-vulnerable-hackers-congress-says\/158024\/\" target=\"_blank\">several <\/a><a href=\"https:\/\/www.wired.com\/story\/federal-government-cybersecurity-bleak\/\" target=\"_blank\">press <\/a>reports. In addition, industry officials <a href=\"https:\/\/www.fifthdomain.com\/show-reporters\/black-hat\/2019\/08\/23\/how-can-the-government-improve-its-cyber-posture\/\" target=\"_blank\">have told Fifth Domain<\/a> that some agencies have so many vendor products on their networks that it obstructs visibility of what\u2019s actually happening.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Grossman said he\u2019s adopted a policy of removing two tools for every one tool the FAA purchases for network security, similar to a rule for adding regulations that\u2019s been set by the Trump administration. The Department of Homeland Security also has \u201ctoo many\u201d cybersecurity products on its network, said Paul Beckman, the agency\u2019s chief information security officer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Beckman said he\u2019s trying to determine a way to measure the best tools deployed on his network.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIf you\u2019re not doing what you purport to do &#8230; it\u2019s something I\u2019m certain not to be reinvesting in next budget cycle,\u201d Beckman said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To help evaluate the effectiveness of the tools, Beckman is using the Lockheed Martin Kill Chain and attack simulation technology. The attack simulation technology allows Beckman to run a cyberattack through his entire network infrastructure and find vulnerabilities within it. By doing so, Beckman can identify which security tools aren\u2019t working.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWhen I\u2019m looking at the phases, I\u2019m asking the question every single time \u2018where\u2019d I catch [the attack]?&#8217;and \u2018what failed?,\u2019&#8221; Beckman said. \u201cBecause if I caught it at the very end &#8230; everything leading up to that has failed me.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If Beckman finds that a security tool is failing continuously, \u201cyou\u2019re going to go out the door.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cAll these things should\u2019ve caught it before it got to Point B \u2014 if it didn\u2019t, why?,&#8217;\u201d Beckman said. \u201cAnd a lot of times it will be a misconfiguration &#8230; but sometimes it\u2019s just not doing what it purports to do and it needs to get out.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Department of Homeland
