Busting email security myths: Zakir Hussain

Zakir Hussain

REMOTE work has made teams rely more than ever on communications like email. With so much focus being placed on this medium, Zakir Hussain, Director and CEO, BD Softthought it would be nice to bust a couple of myths surrounding emails and email security.

Myth #1: All dangerous emails contain links or files.

FALSE. While many dangerous emails do contain links or files, it doesn’t mean that emails that don’t have files can’t be dangerous. Phishing and BEC have become popular threats because they don’t rely on links or files: they use social engineering to accomplish their objectives.

Myth #2: Users’ input is important for complete protection.

DEPENDS. Email security can quickly get complicated. If one wants users to contribute to email security, they need to be regularly trained on the threats they may face. As long as users receive regular training, they can be an invaluable piece of the cybersecurity puzzle.

Myth #3: More control of the parameters means better protection.

DEPENDS. Having more granular filtering parameters certainly gives more flexibility to personalise the filtering preference, but at a cost. The risk is in the time spent personalising. Sure, one could spend three hours a day crafting rules that address problems and be perfectly content. But if one is lacking the time to babysit the filtering, this time sink is not an acceptable tradeoff.

Myth #4: All quarantined emails should be reviewed.

FALSE. When a filtering solution has been set up correctly, one shouldn’t feel the need to check the quarantine daily. Checking the quarantine too frequently is a sign of False Positives, either real or imagined, and should be taken as an indication that something isn’t right.

Myth #5: Spam filtering is complicated.

TRUE. This is kind of true. Email filtering done properly is complicated. Letting all good emails through while blocking all bad emails, is a tough challenge. That doesn’t mean it has to be tough on the users or the IT team. The right email filtering solution should give enough control to personalise the experience but not overwhelm with too many options.
