  What is the Deep and Dark Web? The dark web is a hidden part of the internet not indexed by regular search engines, accessed through specialized browsers like Tor. It hosts both legal and illegal activities, offering anonymity but also posing risks like scams and illicit content. What is the dark web, deep web, and surface web? The Internet is sizable with millions of web pages, databases, and servers all run 24 hours a day. But the so-called "visible" Internet (aka surface web or open web) — sites that can be found using search engines like Google and Yahoo — is just the tip of the iceberg. There are several terms surrounding the non-visible Web, but it's worth knowing how they differ if you're planning to browse off the beaten path. The surface web or open web The open web, or surface web,  is the “visible” surface layer. If we continue to visualize the entire web like an iceberg, the open web would be the top portion that’s above the water. From a statistical st...

Distributed denial of service (DDoS) attacks are a subclass of denial of service (DoS) attacks. A   DDoS attack   involves multiple connected online devices, collectively known as a botnet, which are used to overwhelm a target website with fake traffic. Unlike other kinds of cyberattacks, DDoS assaults don’t attempt to breach your security perimeter. Rather, a DDoS attack aims to make your website and servers unavailable to legitimate users. DDoS can also be used as a smokescreen for other malicious activities and to take down security appliances, breaching the target’s security perimeter. A successful distributed denial of service attack is a highly noticeable event impacting an entire online user base. This makes it a popular weapon of choice for hacktivists, cyber vandals, extortionists and anyone else looking to make a point or champion a cause. DDoS attacks can come in short bursts or repeat assaults, but either way the impact on a website or business can last for days, w...
