Secure your business with CyberHoot Today!!!
Indicators of Compromise (IoC) are pieces of forensic evidence, called IoCs for short, which show potential intrusions on a computer system or network. Cybersecurity professionals search for IoCs to detect and confirm intrusions or other malicious activities conducted by hackers. Security researchers use IOCs to better analyze a particular malware’s techniques and behaviors.
IOCs also provide threat intelligence that can be shared within the security community to help organizations defend themselves, prepare incident response plans, and remediation strategies. Efforts are being made by groups like OpenIOC, STIX, and TAXII (among others) to standardize IOC documentation and reporting.
Examples of an IOC include unusual network traffic, suspicious administrative user account activity, time-of-day login anomalies, suspicious file changes, unusual DNS requests, and Web traffic showing bot behavior. These and other unusual activities allow security teams monitoring the systems and networks to spot malicious actors earlier in the intrusion detection process.
What does this mean for an SMB or MSP?
CyberHoot’s Minimum Essential Cybersecurity Recommendations
The following recommendations will help you and your business stay secure with the various threats you may face on a day-to-day basis. All of the suggestions listed below can be gained by hiring CyberHoot’s vCISO Program development services.
- Govern employees with policies and procedures. You need a password policy, an acceptable use policy, an information handling policy, and a written information security program (WISP) at a minimum.
- Train employees on how to spot and avoid phishing attacks. Adopt a Learning Management system like CyberHoot to teach employees the skills they need to be more confident, productive, and secure.
- Test employees with Phishing attacks to practice. CyberHoot’s Phish testing allows businesses to test employees with believable phishing attacks and put those that fail into remedial phish training.
- Deploy critical cybersecurity technology including two-factor authentication on all critical accounts. Enable email SPAM filtering, validate backups, and deploy DNS protection, antivirus, and anti-malware on all your endpoints.
- In the modern Work-from-Home era, make sure you’re managing personal devices connecting to your network by validating their security (patching, antivirus, DNS protections) or prohibiting their use entirely.
- If you haven’t had a risk assessment by a 3rd party in the last 2 years, you should have one now. Establishing a risk management framework in your organization is critical to addressing your most egregious risks with your finite time and money.
- Buy Cyber-Insurance to protect you in a catastrophic failure situation. Cyber-Insurance is no different than Car, Fire, Flood, or Life insurance. It’s there when you need it most.
Each of these recommendations, except cyber-insurance, is built into CyberHoot’s product and virtual Chief Information Security Officer services.
