In this article, I\u2019ll discuss various tactical measures to navigate the current situation and provide strategic guidance for what to do after the immediate crisis abates.<\/p>\n<p><b><span class=\"body-subhead-title\">The Problem<\/span><\/b><\/p>\n<p>Log4j is a very useful tool incorporated in many Java code applications. There are so many places in code where a programmer wants to take some data and put it into a log, or some other kind of repository, for later action. Log4j does this \u2014 it takes a string and copies it from one place (i.e., the userid field in a login screen) and puts it somewhere else (i.e., the input area for an authentication process). Log4j does much more than a simple copy and paste, it also examines the string and interprets it.<\/p>\n<p>Interpretation is generally risky, because unless the program sanitizes the code, things can go quite wrong. Log4j does not sanitize inputs, leaving servers vulnerable to RCE, which can ultimately lead to your enterprise\u2019s valuable data being exfiltrated and ransomed.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"image\">\n<figure class=\"image-figure\"> <img decoding=\"async\" src=\"https:\/\/www.trendmicro.com\/content\/dam\/trendmicro\/global\/en\/ciso\/21\/l\/apache-log4j-mitigating-risks\/image1.png\" alt=\"Apache Log4j: Mitigating risks\"> <\/figure>\n<\/p><\/div>\n<div>\n<div class=\"richText\" readability=\"49.31455399061\">\n<div readability=\"46.469483568075\">\n<p>Source: <a href=\"https:\/\/xkcd.com\/327\/\" target=\"_blank\" rel=\"noopener\">https:\/\/xkcd.com\/327\/<\/a><\/p>\n<p><b><span class=\"body-subhead-title\">How to mitigate risks<\/span><\/b><\/p>\n<p>To stop the immediate crisis, it\u2019s important to assess your exposure and to implement the proper security tools to discover which code and applications might have the vulnerability. Refer to trusted resources, such as the <a href=\"https:\/\/www.cisa.gov\/uscert\/ncas\/alerts\/aa21-356a\" target=\"_blank\" rel=\"noopener\">Cybersecurity and Infrastructure Security Agency (CISA),<\/a> to identify effective vulnerability assessment tools.<\/p>\n<p>At the code level, there are <a href=\"https:\/\/www.trendmicro.com\/en_us\/business\/products\/hybrid-cloud\/cloud-one-open-source-security-by-snyk.html\">tools to scan<\/a> for the presence of the string \u201clog4j\u201din your source code libraries that have calls to the code.<\/p>\n<p>Next, update and patch the effected libraries. The most current fixed version of Log4j is 2.17.0. Make sure you regularly check the <a href=\"https:\/\/logging.apache.org\/log4j\/2.x\/\" target=\"_blank\" rel=\"noopener\">Apache Foundation<\/a> for the most current fix level<b>. <\/b>As the situation continues to evolve, manually patching and updating can become complex. Leverage a security tool with virtual patching capabilities and an effective intrusion prevention system (IPS) to continually monitor your network for malicious activities.<\/p>\n<p>Lastly, security teams should start building a Software Bill of Materials (SBOM) listing all the components used to construct the application. A SBOM will help us diagnose tainted software beyond whatever we might learn from today\u2019s Software Asset Management Database (SAMDB). Admittedly, many organizations do not have a comprehensive SAMDB today. Fixing that should become a greater priority considering the current problems.<\/p>\n<p><span class=\"body-subhead-title\">Developing a long-term security strategy<\/span><\/p>\n<p>After you\u2019ve implemented measures to stop any immediate risks, consider creating a long-term plan in case something similar occurs in the future. Your plan should address:<\/p>\n<ul>\n<li><span class=\"rte-red-bullet\">Who\u2019s leading the response<\/span><\/li>\n<li><span class=\"rte-red-bullet\">How will you assess your exposure?<\/span><\/li>\n<li><span class=\"rte-red-bullet\">Enhancing visibility across software, servers, and shadow IT (assets not centrally managed)<\/span><\/li>\n<li><span class=\"rte-red-bullet\">Timely communication with key providers about their efforts to mitigate risks<\/span><\/li>\n<li><span class=\"rte-red-bullet\">Establishing a communication channel for reporting issues to make sure nothing is missed<\/span><\/li>\n<li><span class=\"rte-red-bullet\">Updating your business continuity plans (BCP) to limit the impact on the organization<\/span><\/li>\n<li><span class=\"rte-red-bullet\">Preventing teams for burnout. It\u2019s widely reported that IT teams are already experiencing burnout\u2014events like Log4j only add more stress. Ensure that security teams feel adequately supported as remediation can take weeks, or months, depending on the size of your organization.<\/span><\/li>\n<\/ul>\n<p><span class=\"body-subhead-title\">Next Steps<\/span><\/p>\n<p>There\u2019s no shortage of news coverage for Log4j; the nonstop updates and news alerts can become overwhelming. Find a trusted advisor with deep cybersecurity knowledge to keep you appraised of the facts instead of turning to those who rely on sensationalism.<\/p>\n<p>For security teams working around the clock in response to the log4j vulnerability, check out our <a href=\"https:\/\/resources.trendmicro.com\/Log4Shell-Vulnerability-Assessment.html\" target=\"_blank\" rel=\"noopener\">free assessment tool<\/a>.<\/p>\n<p>Follow me on Twitter to continue the conversation: <a href=\"https:\/\/www.twitter.com\/@WilliamMalikTM\" target=\"_blank\" rel=\"noopener\">@WilliamMalikTM.<\/a><\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<section class=\"tag--list\">\n<p>Tags<\/p>\n<\/section>\n<p> <\/main> <\/article>\n<\/div>\n<\/div><\/div>\n<\/div>\n<p> <!-- \/* Core functionality javascripts, absolute URL to leverage Akamai CDN *\/ --> <!--For Modal-start--> <\/p>\n<p> <span>sXpIBdPeKzI9PC2p0SWMpUSM2NSxWzPyXTMLlbXmYa0R20xk<\/span> <\/p>\n<p> <!--For Modal-end--> <!-- Go to www.addthis.com\/dashboard to customize your tools --> <\/body> Read More <a href=\"https:\/\/www.trendmicro.com\/en_us\/ciso\/21\/l\/apache-log4j.html\">HERE<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Explore tactical measures and strategic guidance to mitigate ongoing risks caused by Apache Log4j (Log4Shell).
