Secure Shell (SSH) is a cryptographic network communications protocol for operating network services securely over an unsecured network. Typical applications include remote command-line, login, and remote command execution, but any network service can be secured with SSH. This service is generally used by Linux and is the linux/unix command line remote access solution that pairs well with 2FA and public/private key access. It is encrypted and has secure encrypted file sharing capabilities as well with SCP (Secure Copy) and even a windows client known as Putty (also free).
What Should My SMB Do?
If you own a business, you need to be doing these basic things to protect your sensitive information:
- 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, 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, etc) 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.
Most of these recommendations are built into CyberHoot. With CyberHoot you can govern, train, assess, and test your employees. Visit CyberHoot.com and sign up for our services today.
