Interview with Philippe Courtot, CEO, Qualys

Situation: Companies experiencing security breaches and data theft are regularly in the headlines. Those launching these attacks are increasingly well organized and very creative. What is changing the game in network security and how can you respond?

Advice from Philippe Courtot:

• The movements from enterprise software to Software as a Service (SaaS), and from mainframes to PCs to mobile devices increase the challenges of protecting enterprise environments. Therefore, a cohesive technology platform is imperative.
• Companies are sensitive to the possibility of attack at any time. There are three principal attack vectors: breach through web applications, breach through email and browsers, and breach by device. Between PCs, iPhones and Android devices, the PC is the most closely linked to the corporate intranet while often the most vulnerable because users are lax about updating their systems and applications.
• Attackers often target a company executive or high level administrative assistant to access the user’s profile and passwords.  In one type of attack called spear fishing, the attacker creates emails tailored to the person targeted appearing to come from a colleague or friend. When the target clicks on the email, a small piece of code is inserted in the computer, which can give control to the attacker. Another way to gain control of a computer is through physical access. An attacker can learn about a pending vacation via Facebook or twitter, providing an opportunity for home invasion. Once the attacker has access to the computer, they can plant a control program on the system. When the user returns, the attackers can make fast, brief forays inserting additional code or taking data from the enterprise network. They may use the information themselves, or sell it to others.

Given these new realities, how does a company prevent attack?

• First, the company must thoroughly analyze and understand their vulnerabilities which are all potential entry points for an attacker. Once vulnerabilities are mapped, work on a schedule to remediate them.

• Second, you must educate all users about the threats. This is especially critical for any personnel who have access to secure company data.
• Third, invest in and build additional defenses to shield all remaining vulnerabilities. Make sure that employees are drilled on the defenses and that they are used. One growing trend is the use of two factor authentication, requiring employees to carry token generation devices with them to use in addition to their password. These tokens can be delivered by smart phone.
