Every day, more than 1 million people become victims of cyber crime, according to a study by Symantec, a computer security software company. Businesses, both large and small, are increasingly reliant on the Internet for daily operations, creating attractive and potentially lucrative targets for cyber criminals.
With such heavy use of and reliance on computers and the Internet by both large and small organizations, protecting these resources has become increasingly important. Learning about cyber attacks and how to prevent them can help you protect your company from security breaches.
Cyber Attacks Compromise Your Company
Cyber attacks include many types of attempted or successful breaches of computer security. These threats come in different forms, including phishing, viruses, Trojans, key logging, spyware and spam. Once hackers have gained access to the computer system, they can accomplish any of several malicious goals, typically stealing information or financial assets, corrupting data or causing operational disruption or shut-down.
Both third parties and insiders can use a variety of techniques to carry out cyber attacks. These techniques range from highly sophisticated efforts to electronically circumvent network security or overwhelm websites to more traditional intelligence gathering and social engineering aimed at gaining network access.
Cyber attacks can result directly from deliberate actions of hackers, or attacks can be unintentionally facilitated by employees—for example, if they click on a malicious link.
A breach in cyber security can lead to unauthorized usage through tactics such as the following:
Installing spyware that allows the hacker to track Internet activity and steal information and passwords
- Deceiving recipients of phishing emails into disclosing personal information
- Tricking recipients of spam email into giving hackers access to the computer system
- Installing viruses that allow hackers to steal, corrupt or delete information or even crash the entire system
- Hijacking the company website and rerouting visitors to a fraudulent look-alike site and subsequently stealing personal information from clients or consumers
Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as denial-of-service attacks on websites in which the site is overloaded by the attacker and legitimate users are then denied access.
The Vulnerable Become the Victims
The majority of cyber criminals are indiscriminate when choosing their victims. The Department of Homeland Security (DHS) asserts that cyber criminals will target vulnerable computer systems regardless of whether the systems belong to a Fortune 500 company, a small business or a home user.
Cyber criminals look for weak spots and attack there, no matter how large or small the organization. Small businesses, for instance, are becoming a more attractive target as many larger companies tighten their cyber security.
Simple Steps to Stay SecureThe DHS, which issues bulletins and alerts that provide information on potential cyber threats, has issued more than 5,000 alerts and advisories in a single year. With cyber attacks posing such a prominent threat to your business, it is essential to create a plan to deal with this problem. Implementing and adhering to basic preventive and safety procedures will help protect your company from cyber threats.
Following are suggestions from a Federal Communications Commission roundtable and the DHS’s Stop.Think.Connect. program for easily implemented security procedures to help ward off cyber criminals. These suggestions include guidelines for the company as well as possible rules and procedures that can be shared with employees.
Security Tips for the Company
Install, use and regularly update anti-virus and anti-spyware software on all computers.
- Download and install software updates for your operating systems and applications as they become available; if possible, choose the automatic update option.
- Change the manufacturer’s default passwords on all software.
- Use a firewall for your Internet connection.
- Regularly make backup copies of important business data.
- Control who can physically access your computers and other network components.
- Secure any Wi-Fi networks.
- Require individual user accounts for each employee.
- Limit employee access to data and information, and limit authority for software installation.
- Monitor, log and analyze all attempted and successful attacks on systems and networks.
Security Tips for Employees
- Use strong passwords (a combination of uppercase and lowercase letters, numbers and special characters), change them regularly and never them share with anyone.
- Protect private information by not disclosing it unless necessary, and always verify the source if asked to input sensitive data for a website or email.
- Don’t open suspicious links and emails; an indication that the site is safe is if the URL begins with https://.
- Scan all external devices, such as USB flash drives, for viruses and malicious software (malware) before using the device.
Most importantly, stay informed about cyber security and continue to discuss Internet safety with employees.
Don’t Let it Happen to Your Company
According to the DHS, 96 percent of cyber security breaches could have been avoided with simple or intermediate controls. Strengthening passwords, installing anti-virus software and not opening suspicious emails and links are the first steps toward cyber security.
