MYTH: “A ‘port scan’ is the same thing as a security analysis scan and some web sites already give me that for nothing.”
FACT: Actually a port scan and a security analysis scan are two very different things. In general terms your computer's Internet connection has 65,535 unique service ports. These ports are used both by software running on your computer and by remote servers sending data to your computer (when you view a web page or check your email). A port scan will simply tell you which service ports are being used on your computer. It does not test any of these ports for security threats nor does it tell you where your network is vulnerable to possible hackers or attacks.
MYTH: “The best time to deal with network security is when a problem arises.”
FACT: The best time to deal with network security is right now, before a problem arises and to prevent you from ever becoming a victim. Think about it – the best time to lock the doors in your home is before a robbery occurs. Afterwards it is already too late, the damage has been done. This is why it is critical to analyse your network's security now, to find and fix the vulnerabilities before a break-in happens.
