NETWORK SECURITY 101
HOW DO HACKERS GET ACCESS? • KEYLOGGERS is one of the basic tools used for getting passwords and other information. Keylogger resides in your system memory and runs at every startup. These keyloggers log all the keystrokes you type. A log is created and then it is sent to the Hacker. It can be customized so that it cannot be shown in “processes” (Windows Task Manager). • RAT (Remote Administration Tool) where a hacker can connect to your PC without your knowledge. He can see what is going on the screen, what you are currently doing, which sites you surf. It also has a built-in functionality of keylogger. Hacker can copy files from your hard disk to his computer, and all of this without your knowledge. • TROJAN HORSE most common types of malwares. Trojans spread through warez sites mostly. We all want FREE software right? When you download from a warez site, all the keygens and patches and even the original trial programs are trojaned. • RANSOMWARE is when a malicious code locks up computer files and cybercriminals demand a ransom to free them.
AS EASY AS 1…2…3 BEING AFFECTED IS EASY AS 1…2…3 How so?  Opening email (at times, even from a name that you recognize)  Downloading an application  Downloading computer updates  Your internet and email are the two most dangerous sources for security breaches
WHY SMALL BUSINESS? • In 2014, 60% of all online attacks targeted small and mid size businesses* • Once affected, small and mid size businesses spent an average of $8,700 repairing the damages* • Small businesses are particularly vulnerable to attacks because many owners believe they don’t have the time and resources to invest in setting up proactive barriers
THE REALITY OF MANY BUSINESSES
SYMPTOMS TO WATCH OUT FOR • Highlighted links on web pages • Internet speed latency • Unwanted pop-ups • Unscheduled reboot • Operating system warnings that don’t come from operating system • Increase in junk mail • Unrecognized files
