PHISHING BIGGEST CYBER THREAT – PROTECT THE DNS WAY!
Given the nature of the increase in the phishing attacks, I think this term is being used more extensively than its original, fishing. The world is under total transformation and cyber threat has been completely changing the way we view crime. FedEx / Investment online scams have led people to lose crores at one end and still escape unscathed, the quantum of booty which would have been impossible in the physical world. Gaining access to your system is the first step to commit cyber-crime. Phishing is the practice of sending fraudulent communication that seems to be coming through a reputable source.
Generally deployed by email, the purpose is to steal critical data or install malware. As it stands today 86% of organisations have had at least one user try to connect to a phishing site. Phishing attacks account for 90% of the data attacks. Besides phishing, malware, the nature of command & control traffic and malicious crypto mining are together putting the cyber world upside down. Billions of ever-expanding connections every day, which one’s are suspicious is the question. There are more things to protect than ever before. The Domain Name System, DNS, is the phone book of the internet. A proper tab on it can certainly improve matters.
DNS helps connect to websites, perform software updates and use many of the applications organisations rely on. It is seen that most organisations don’t bother to secure the DNS layer, it is likely that they are missing the opportunities to block cyberattacks. A recent report titled “Value of DNS Security” found that 1 out of 3 breaches could have been contained by the DNS. It is true that DNS layer security would have helped in preventing major losses to the tune of millions. This report also explains how DNS layer security provides better accuracy and detection of malicious activity and compromised systems.
DNS-layer security benefits are concrete in terms of results. Enforcing security at the DNS layer through market leading tools blocks requests to malware, ransomware, phishing, and botnets before a connection is established. It increases security visibility and network protection. It helps in proactively responding to threats. The tool, take for example Umbrella, logs all DNS activity to simplify investigations. Cisco’s Umbrella simplifies security management. The DNS-layer protection reduces the number of infections and alerts, which is done by stopping threats at the earliest point.
DNS-LAYER SECURITY IF SEEN THROUGH HAS THE POTENTIAL OF REDEFINING CYBER SECURITY.
