DIY Protection Against Malicious Code

Advice You Can UseThe recently revised Security Tip (ST18-004) provides a good review of malicious code and ransomware, as well as their impact, and prevention and mitigation. It was posted by the Department of Homeland Security’s National Cybersecurity and Communications Integration Center (NCCIC). Since 2009, NCCIC has served as a national hub for cyber and communications information, technical expertise, and operational integration. You likely have few to no cybersecurity experts on your IT staff. In my last No Jitter blog, I took a look at the cyber security skills gap and what businesses and individuals can do to counter it. But it’s a big gap, and it will not be closed easily or quickly. In the meantime, you need to do as much as possible with your current staff to prevent attacks. Current Activity – provides current information about high-impact types of security activity affecting the larger communityAlerts – supply information about security issues, vulnerabilities, and exploitsBulletins – give weekly summaries of new vulnerabilities and available patch informationTips – offer advice about common security issues for the general publicAnalysis Reports – provide analysis on new or evolving cyber threats Malicious Code ClassificationsMalicious code can harm your computer and compromise your data. They are unwanted files and programs. There are four broad classifications of malicious code: Where to LookThe National Cyber Awareness System offers information for users who have varied technical expertise: The software you select should perform automatic scans. If this is an option, definitely enable it. If automatic scans are not possible with your selected antivirus software, make a habit of doing regular manual scans, especially when you are receiving files and media from external sources. IT Security Refresh: The Cyber Defense Matrix Terry Slattery October 02, 2019 With the Cyber Defense Matrix, enterprises can measure their security coverage and discover gaps in their IT strategy. Log in or register to post comments Did you know that the antivirus programs in your Android device likely don’t work the way they should? This is according to a recent test by AV-Comparatives that found only 80 of the 250 antivirus apps tested for Google’s platform passed basic standards. If you’re working remotely, disconnect your computer from the Internet. This will prevent the attacker from accessing your system. If you think there is malicious code in your computer, you should perform a manual scan of your entire system. If your software cannot locate and remove the malicious code, you may have to reinstall your operating system. Insurance?You likely don’t want to pay for insurance — it’s expensive! But it may help cover your costs, and will force you to follow effective practices (see “Cybersecurity Insurance” from the Department of Homeland Security). Ensure that your users are cautious when clicking links and opening attachments that are unsolicitedAdequately train your users in security and periodically verify their compliance with your best practicesBlock pop-up advertisementsLimit user permissionsDisable the ability to run external media featuresChange passwords frequently and ensure that they are not easily discoveredKeep software updatedBackup data periodically, not just a few times a yearMonitor accounts and activities, looking for unauthorized use or unusual activityEnsure that your users limit what they do with public Wi-Fi and discourage use, if possible Does Antivirus Work?You need to install and maintain antivirus software. Don’t assume that all software is the same or is equally protective. Keep the antivirus software up to date, and never delay updates. If you install more than one antivirus software solution in your enterprise environment at the same time, you may find that the software of each program competes with the other and slows down your operation. Cybersecurity insurance can mitigate losses from a variety of cyber incidents, such as data breaches, business interruption, and network damage. Insurance suppliers can also ensure a business adopts preventative measures in return for insurance coverage. Insurers will encourage the implementation of best practices and base premiums on an insured’s level of self-protection. Even if you do not buy insurance, look into the insurer’s requirements, as they will inform you about what they think are the best practices your enterprise should be implementing. You can use their requirements for insurance as a security best practices benchmark.Tags:News & Viewscybersecuritymalicious codeantivirus softwarecybersecurity insuranceSecurityAI & AutomationBest PracticesEnterprise NetworkingMonitoring, Management and SecurityOrganization & Management Articles You Might Like Protection RecommendationsAssuming that your enterprise will not be able to add more security staff, you need your current IT staff to implement measures that can protect your environment. Such protections will not guarantee a safe and secure environment, but they will definitely reduce your security liabilities. These are the best practices to follow: As an example, a recent alert covers the WPA3 protocol design and implementations of hostapd and wpa_supplicant, which allow a remote attacker to acquire weak passwords, institute a denial of service, or gain complete authorization to the network. These vulnerabilities have also been referred to as Dragonblood.
