According to the survey of more than 100 information security professionals, 66 % of respondents cited human error in the configuration of network security devices as the most common cause of outages in the past 12 months, followed by capacity overload (14 %) and flaws in the gateway product (9 %).
The majority of respondents said they had from 10 to 49 different security gateways installed on their network. Another 15 % of companies had more than 50 security gateways installed.
The most common security gateways were firewalls, installed on 98 % of corporate networks, along with anti-virus (90 %) and content filters (85 %). #
Among these devices, respondents said that firewalls required the greatest investment of time and were held responsible for causing the most network disruptions. A full 73 % of respondents cited a “high number of changes” as the primary reason for the large time investment in managing security gateways.
Given the complexity of the networks we deal with this shouldn’t be shocking. How often have we seen misconfiguration of network devices cause security problems? How often have we seen entire networks taken down by someone innocently plugging a device into the wrong port?
Its true that common sense cant be taught. But good management practices (including adequate supervision of network device configuration, change control, validation, and documentation) can go a long way to decreasing the network security problems attributed to human error.
Security Change Management is a big challenge Firewalls take up the most management overhead (hardly a surprise for us of course), with 73.1 % (!) citing a high number of changes as the main cause for the time investment.
If there is one key take away from the survey, I think it is that organizations must be aware of the impact of security configuration errors and take steps to minimize them. Here are some points to consider:
- xBL.Factor-in ease of use when selecting security products Which of the two do you prefer – a great security product that is misconfigured or a good security product that is well configured? Make sure to give ample weight to ease of management and configuration when selecting security products.
- Continuous training it’s not enough to train your security and operations team when you first deploy a new technology. Make sure you allocate the time and budget to ensure security staff is up to speed with latest know how.
- Automate as much possible automation is not only about operational efficiency, it ‘s also about reducing errors. Invest in tools that can help you automate security configuration and or discover configuration errors.
- Review change management processes change.
