Discretionary Access Controls (DAC)

Discretionary Access Controls, also known as DAC, are types of cybersecurity measures that allow or restrict access based upon the discretion of the file or resource owner. For example, if Bob owns a file or resource, then Bob can, at his discretion grant access to Susie and deny access to Jennifer.  These controls are discretionary because the owner determines the access entitlements.  In contrast to DAC, mandatory access controls (or MAC) are controls established by a company or organization and enforced at the entity level on the employees or workers within that organization.

What Does This Mean For My SMB?

In addition to setting up DAC in your business, you need to be doing these things to protect your sensitive information:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
