Hackers are hell-bent on busting into the network of their targets. They are persistent-never giving up. When you build your defense against cyber criminals, it must be done with the idea that they WILL succeed. When you operate on this assumption rather than thinking that your anti this and anti that are all you need, you'll have the best cyber security in place.
Another mistake is to assume that hackers hound only small businesses or weak networks. The cyber criminal doesn't care so much about vulnerabilities; he wants the goods. It's like a burglar wanting a million dollars worth of jewels that he knows is stashed inside a mansion surrounded by a moat filled with crocodiles. This won't stop him. It will only determine the dynamics of how he penetrates.
Yes, less sophisticated hackers will target more vulnerable networks, but there's a lot of hefty hackers out there who aren't intimidated by persistence. If cyber thieves want a goal badly enough, they'll get into every nook and cranny to achieve their mission.
Hackers also determine ahead of time how the victim might respond to an attack. The crime ring will invest time in this, going well-beyond the intended target's IT tactics. They'll go as far as learning employees' after-hour leisure activities. To make it harder for hackers to mine all this information, a company should keep things unpredictable like work routines and not embrace social media.
The hacker creeps around quietly, going undetected while spreading damage. To catch below-the-radar cyber invasions, a business should employ a system that can spot and stamp out these murmurs.
Finally, cyber criminals usually launch a secondary attack as a distraction while the major attack gets underway-kind of like that newsworthy operation of some years ago involving pairs of thieves: One would approach a woman with a baby and tell her the baby was ugly. This distracted her so much that she had no idea that the accomplice was slipping off her purse and scrambling away with it. You must anticipate decoy operations.
Remember, install layers of protection:
