Even if you are bound to follow the <a href="/rules/en/index.shtml">Computing Rules</a></b>, you might lack knowledge, means and expertise to do so. Therefore, this page puts all relevant information at your disposal. If this is not sufficient, you might want to join one of our <a href="/training/en/index.shtml">training courses</a> or take advantage of our <a href="/services/en/index.shtml">services</a>.</p> <h4>For All Users (Experts or Not)</h4> <p>Some security issues can be sophisticated and tricky, but larger fraction of the standard problems are rather basic and simple. On the sidebar, users, beginners, experts - everyone - can find basic and simple tips & tricks on how to use your computer securely. Usually, it takes just a bit of awareness and alertness to protect yourself against the most frequent security threats...</p> <h4>For Software Developers</h4> <p>Writing software is not always as easy as it seems. CERN users are quite creative and the academic freedom allows you to chose the way you want to program. However, security events in the past have shown that, while the functionality has properly been implemented, security measures lack completely. Thus, if you feel your code needs improvement in this respect, on the sidebar, you'll find all the necessary help, advise and tools you need.</p> <h4>For System Owners</h4> <p>Being owner of a system or service increases the scope of responsibility, in particular with view on availability and security. Both go hand-in-hand, and a security event can have large (negative) impact on a system or service (<i>How long does it take you to reinstall your system/service?</i>). The topics on the sidebar are providing you check-lists for verifying the security of your systems and services.</p> </div>    <div id="sidebar"> <h3>For All Users<br/> (Experts or Not)</h3> <ul class="sidemenu"> <li><a href="/recommendations/en/good_practises.shtml">Seven easy good practises</a></li> <li><a href="/recommendations/en/how_to_secure_your_pc.shtml">How to secure your PC or Mac</a></li> <li><a href="/recommendations/en/passwords.shtml">Passwords & toothbrushes</a></li> <li><a href="/recommendations/en/2FA.shtml">Starting with multi-factor authentication</a></li> <li><a href="/recommendations/en/bad_mails.shtml">Bad mails for you:<br/>"Phishing", "SPAM" & fraud</a></li> <li><a href="/recommendations/en/malicious_email.shtml">How to identify malicious e-mails and attachments</a></li> <li><a href="/recommendations/en/how_to_remove_malicious_browser_notifications.shtml">How to remove malicious browser notifications</a></li> <li><a href="/recommendations/en/working_remotely.shtml">Working remotely</a></li> <li><a href="/recommendations/en/connecting_to_cern.shtml">Connecting to CERN</a></li> <li><a href="/recommendations/en/ssh.shtml">Connecting using SSH</a></li> </ul> <h3>For Software Developers</h3> <ul class="sidemenu"> <li>Good programming in <a href="/recommendations/en/program_c.shtml">C/C++</a>, <a href="/recommendations/en/program_java.shtml">Java</a>, <a href="/recommendations/en/program_perl.shtml">Perl</a>, <a href="/recommendations/en/program_php.shtml">PHP</a>, and <a href="/recommendations/en/program_python.shtml">Python</a></li> <li><a href="/recommendations/en/password_alternatives.shtml">How to keep secrets secret<br/> (alternatives to passwords)</a></li> <li><a href="/recommendations/en/checklist_for_coders.shtml">Security checklist</a></li> <li><a href="https://gitlab.docs.cern.ch/docs/Secure%20your%20application/">GitLab CI Security Tools</a></li> <li><a href="/recommendations/en/web_applications.shtml">Securing Web applications</a></li> <li><a href="/recommendations/en/code_tools.shtml">Static code analysis tools</a></li> <li><a href="/recommendations/en/more_on_software.shtml">Further reading</a></li> </ul> <h3>For System Owners</h3> <ul class="sidemenu"> <li><a href="/recommendations/en/rootkits.shtml">Checking for rootkits</a></li> <li><a href="https://twiki.cern.ch/twiki/bin/viewauth/CNIC/WebHome">Securing Control Systems (CNIC)</a></li> <li><a href="/recommendations/en/containers.shtml">Securing Containers & Pods</a></li> <li><a href="/rules/en/baselines.shtml">Security baselines</a></li> <li><a href="http://linux.web.cern.ch/linux/docs/linux_exploit_faq.shtml"> The CERN Linux vulnerability FAQ</a></li> </ul> </div>   </div>  <div id="footer-wrap"> <div id="footer-bottom"> © Copyright 2024<strong> <a href="https://cern.ch/security">CERN Computer Security Office</a></strong> <table> <tr> <td id="footer-info-left"> e-mail: <a href="mailto:Computer.Security@cern.ch">Computer.Security@cern.ch</a><br/> Please use the following PGP key to encrypt your messages:<br/> ID: 0x954CE234B4C6ED84<br/> <a href="https://keys.openpgp.org/vks/v1/by-fingerprint/429D60460EBE8006B04CDF02954CE234B4C6ED84">429D 6046 0EBE 8006 B04C DF02 954C E234 B4C6 ED84</a> </td> <td id="footer-info-right"> Phone: +41 22 767 0500<br/> Please listen to the recorded instructions. </td> </tr> </table> </div> </div>  </div>   </body> </html>
