Compliance with PCI-DSS is crucial for maintaining the security and integrity of sensitive payment card information. Failing to meet the requirements of PCI-DSS can have significant implications for a company, including legal and financial consequences.

One specific requirement of PCI-DSS is 1.1.7, which addresses the need to test security systems and processes regularly. Failing to comply with this specific requirement can result in severe penalties, including hefty fines and potential legal action. Companies may also face damage to their reputation and loss of customer trust. In some cases, non-compliance with PCI-DSS requirements may lead to the inability to process payment card transactions, causing significant operational disruptions. Ultimately, the consequences of failing to meet PCI-DSS 1.1.7 can have far-reaching impacts on a company’s bottom line and long-term viability. Therefore, businesses must prioritize and invest in maintaining compliance with PCI-DSS to avoid these detrimental consequences.

Importance of securing inbound traffic

Securing inbound traffic is critical for maintaining the cardholder data environment’s security and integrity, as PCI DSS Requirement 1.2.1 mandates. Organizations can effectively prevent unauthorized access and potential security breaches by limiting inbound and outbound traffic to only what is necessary for the cardholder data environment. Traffic restrictions are crucial in controlling and monitoring data flow into the network, ensuring that only authorized and necessary sources and protocols are allowed entry. This helps to minimize the risk of unauthorized access and potential security breaches, as any unnecessary or unauthorized traffic is blocked from entering the network. By implementing and enforcing these traffic restrictions, organizations can significantly reduce the likelihood of data breaches and maintain compliance with PCI DSS standards. Therefore, organizations must prioritize and effectively secure their inbound traffic to safeguard their cardholder data environment.

Importance of securing outbound traffic

Securing outbound traffic is paramount for protecting an organization’s sensitive information and preventing potential risks such as data breaches, exposure to malware, and unauthorized access to critical data.

Leaking RFC1918 IP Addresses to the Internet

Posted on June 15, 2017 by Brent Huston

There has been a lot of conversation with clients about exposing internal DNS information to the public Internet lately.

There are some security considerations, and a lot of the arguments often devolve into security by obscurity types of control discussions. My big problem with the leakage of internal DNS data to the Internet is that I hypothesize that it attracts attacker interest. That is, I know when I see it at a client company, I often immediately assume they have immature networking practices and wonder what other deeper security issues are present. It sort of makes me deeper attention to my pen-testing work and dig deeper for other subtle holes. I am guessing that it does the same for attackers.

Of course, I don’t have any real data to back that up. Maybe someone out there has run some honeypots with and without such leakage and then measured the aggregate risk difference between the two scenarios, but I doubt it. Most folks aren’t given to obsess over modeling like I am, and that is likely a good thing.

It turns out though, that there are other concerns with exposed internal DNS information. Here are a few links to those discussions, and there are several more on the NANOG mailing list from the past several years.

Server fault, Quora, and, of course, the RFC1918 that says you shouldn’t leak them. 🙂

So, you might wanna check and see if you have these exposures, and if so, and you don’t absolutely need them, then remove them. It makes you potentially safer, and it makes the Internet a nicer place. 🙂

If you have an actual use for leaking them to the public Internet, I would love to hear more about it. Hit me up on Twitter and let me know about it. I’ll write a later post with some use scenarios if folks have them.

Thanks for reading!
