Protecting your computer against hacking is different from protecting it against viruses that you accidentally or unknowingly invite into your computer that then cause damage in one form or another. Anti-hack is about protecting your computer against external entities that are deliberately trying to get into your computer to cause damage and to steal from you – or cause damage. Viruses are impersonal and hacking is personal.

Anti-Hack software is now out there for sale in addition to anti-virus software. These products protect you in ways that anti-virus software does not. Following are some examples.

DoS (Denial of Service) Attacks:

DoS attacks occur when too much traffic is directed to your company website at once. The web server essentially ‘chokes’ on the amount of traffic trying to squeeze into it’s network hardware. Attack scripts are easily downloadable and you do not need to be an experienced engineer to launch an attack. Upset customers seeking some sort of revenge or disruption, الحصول على جواهر فري فاير interrupting your site, or these days, as in the recent major hospital attacks, the trend is to hold your web site hostage until some ransom is paid or some demand met. “Ransomeware” is a relatively new term, but it is gaining a lot of visibility in recent times.

SNMP (Simple Network Management Protocol) Attacks:

Akamai’s Prolexic Security Engineering and Response Team (PLXsert) recently issued a threat advisory warning of DDoS (Distributed Denial of Service) attacks abusing the Simple Network Management Protocol (SNMP) interface. PLXsert SNMP DDoS attack campaigns target various industries including consumer products, gaming, hosting, nonprofits, and software-as-a-service, mainly in the US (49.9%) and China (18.49%). The attackers used an online tool posted by the hacker group ‘Team Poison’. This latest wave of attacks targets devices running SNMP which by default is open to the public Internet unless that feature is manually disabled. Anti-hack software is now being created that help prevent SNMP attacks such as this by preventing the attacker from forcing network switching to secondary gateways.

SYN/AWK Attacks:

This is a little complex but basically, a SYN flood attack is similar to a Denial of Service attack in that there is request made to the web server that ties up its resources and makes it unavailable to other connections. When a computer or web browser tries to connect to a web site, what’s called a 3-way handshake is used to establish the connection between the two computers. In a SYN/AWK Flood attack, the computer offers its hand (1-way), the server reaches out to meet it (2-way) but the offered hand is quickly withdrawn. The server waits for the hand to come back until it ‘times-out’ and then the cycle repeats millions of times. The 3-way handshake is never established and all other connections are refused while this is happening.
