Security Check List: An Ounce of Prevention is Better than a Pound of Cure
Blog Article Published: 04/30/2013
By Wolfgang Kandek It is common belief that buying more robust and expensive security products will offer the best protection from computer-based attacks; that ultimately the expenditure pays off by preventing data theft. According to Gartner, more than $50 billion is spent annually on security infrastructure software, hardware and services. They expect this number to continue to grow and reach $86 billion by 2016. With security investments skyrocketing, the number of successful attacks should be decreasing but they aren’t. That’s the reality. There is no one thing or even combination of things that can guarantee you won’t get hacked. However, there are some basic precautions companies can take that can put up enough defenses to make it not worth a hacker’s time and effort to try to break in. The recent Verizon Business 2013 Data Breach Investigations Report revealed that 78 percent of initial intrusions were rated as low difficulty and likely could have been avoided if IT administrators had used some intermediate and even simple controls. Using outdated software versions, non-hardened configurations and weak passwords are just a few of the many common mistakes businesses make. These basic precautions are being overlooked, or worse, ignored. Implement a security hygiene checklist One of the most simple and effective way for companies to improve their defenses is to create and closely adhere to a checklist for basic security hygiene. The Centre for the Protection of National Infrastructure in the UK and the Center for Strategic & International Studies (CSIS) in the U.S. released a list of the top 20 critical security controls for defending against the most common types of attacks. Topping the list are creating an inventory of authorized and unauthorized devices and software, securing configurations for hardware and software, and continuous vulnerability assessment and remediation. A laundry list of organizations are already using this checklist and seeing results, including the U.S. Department of State, NASA, Goldman Sachs and OfficeMax. The State Department followed the guidelines for 40,000 computers in 280 sites around the world and within the first nine months, it reduced its risk by 90 percent. In Australia, the defense agency’s Department of Industry, Innovation, Science, Research and Tertiary Education reported that it had eliminated 85 percent of all incidents and blocked malware it would have missed otherwise, without purchasing additional software or increasing end user restrictions. My own security precaution checklist includes:
- Promptly apply security patches for applications and operating system to keep all software up to date
- Harden software configurations
- Curtail admin privileges for users
- Use 2-factor authentication for remote access services
- Change default admin passwords
- And prohibit Web surfing with admin accounts
- Friendly competition – One engineer at NASA boosted participation by awarding badges, points and other merits as if it were a game, giving employees incentive to compete for the highest score.
- Company-wide report card - The Department of State assigns letter grades based on threat risk for each location including various aspects of security and compliance. For instance, a lower grade would be given for software that is missing critical patches and infrequent vulnerability scanning. The report cards are published internally for all locations to see and again boost participation by competition and cooperation.
- Show them the money - The biggest incentive of all would be offering bonuses or time off for quantifiable improvements in security and reduced risk.
