As the Vice President of Compliance and Policy at fTLD Registry Services, Heather Diaz is a security expert with over a decade of experience in ensuring the legal, compliance, and strategic alignment of the top-level domains .Bank and .Insurance. She is a compliance and ethics professional and leads the policy and security compliance functions at fTLD.
We sat down with her to learn more about how Zabbix makes her job easier, why she appreciates the inherent flexibility of our solutions, and how she works with our team to help make sure fTLD’s domains are as secure as they can possibly be.
Can you give us a bit of background on fTLD and what it does? What makes your business proposition stand out?
fTLD Registry is the domain authority for .Bank and .Insurance – the most trusted and exclusive domain extensions for banks, insurers, and producers. Our mission is to offer these industry-created and governed domains a shield against cyberattacks and fraud, delivering peace of mind with website and email security.
Since 2011, fTLD Registry has collaborated with experts in cybersecurity, domain security, and the banking and insurance sectors to develop Security Requirements that mitigate cyber threats such as phishing, spoofing, cybersquatting, and man-in-the-middle attacks.
Why is monitoring especially important for fTLD?
Security monitoring is a key value for .Bankers (banks who have switched to .Bank) and our .Insurance customers as well. They receive reporting from our customized Zabbix monitoring system whenever security vulnerabilities are detected. This ensures we provide proactive compliance security monitoring, which allows them to address any findings and keep their .Bank and .Insurance websites and email channels secure.
Are there any specific points you were looking to address with a new monitoring approach?
fTLD has continued to enhance our security requirements for .Bank and .Insurance to address new and evolving cybersecurity threats and provide more secure and trusted online interactions for the financial services sector and their customers. We do this by partnering with Zabbix’s security experts and engineers to make sure our security requirements and monitoring continue to provide best-in-class domain security for .Bank and .Insurance.
Can you please share any business or operational areas that have seen improvements since implementing Zabbix?
Our compliance area has enjoyed having time to engage with .Bank and .Insurance customers to educate them about how to address any security vulnerabilities, as the Zabbix system takes care of sending notifications and warnings to our customers. Not only that, the Zabbix system gives us a dashboard with easy-to-interpret metrics, the ability to generate ad-hoc reporting, and with a number of important data elements integrated, such as customer contact information and their domain status (e.g., live), so our team can always have secure employee access to security monitoring data no matter where in the world we are working. Here are just some of the external interfaces, Agent2 plugins, and custom notifications we developed together with the Zabbix team.
External interfaces:
ICANN CZDS (to get a list of zones)
Whois (to get zone and registrar details)
CRM (to get a list of verification contacts)
Marketing system (to get a list of additional zone details)
Certificate plugin (to validate TLS ciphers and certificates)
Port check plugin (to check what ports are open and verify the security of opened ports)
DMARC/SPF plugin (to check presence and validity of DMARC and SPF records)
Web redirect plugin (to check validity of HTTP headers and redirects)
Notifications
Media types to send compliance reports
Is there anything else you’d like to share about Zabbix and our capabilities?
Zabbix is a great partner for security monitoring, as they’re willing to develop new features to provide a service that meets our exacting business requirements and their support is highly responsive. Most solutions come as they are. With Zabbix, we were able to customize and adapt their solution when new needs came up. My favorite feature is how we provide automated reporting to our customers and key stakeholders – it’s all automated and handled by the Zabbix platform.
The Internet can feel like magic. When you load a webpage in your browser, many simultaneous requests for data fly back and forth to remote servers. Then, often in less than one second, a website appears. Many people know that DNS is used to look up a hostname, and resolve it to an IP address, but fewer understand how data flows from your home network to the network that controls the IP address of the web server.
The Internet is an interconnected network of networks, operated by thousands of independent entities. To allow these networks to communicate with each other, in 1989, on the back of two napkins, three network engineers devised the Border Gateway Protocol (BGP). It allows these independent networks to signal directions for IP prefixes they own, or that are reachable through their network. At that time, Internet security wasn’t a big deal — SSL, initially developed to secure websites, wasn’t developed until 1995, six years later. So BGP wasn’t originally built with security in mind, but over time, security and availability concerns have emerged.
BGP is the core signaling protocol used on the Internet. It’s fully distributed, and managed independently by all the individual operators of the Internet. With BGP, operators will send messages to their neighbors (other networks they are directly connected with, either physically or through an Internet Exchange) that indicate their network can be used to reach a specific IP prefix. These IP prefixes can be resources the network owns themselves, such as 104.16.128.0/20 for Cloudflare, or resources that are reachable through their network, by transiting the network.
By exchanging all of this information between peers, each individual network on the Internet can form a full map of what the Internet looks like, and ideally, how to reach each IP address on the Internet. This map is in an almost constant state of flux: networks disappear from the Internet for a wide variety of reasons, ranging from scheduled maintenance to catastrophic failures, like the Facebook incident in 2021. On top of this, the ideal path to take from point A (your home ISP) to point B (Cloudflare) can change drastically, depending on routing decisions made by your home ISP, and any or all intermediate networks between your home ISP and Cloudflare (here’s an example from 2019). These routing decisions are entirely arbitrary, and left to the owners of the networks. Performance and security can be considered, but neither of these have been historically made visible through BGP itself.
As all the networks can independently make their own routing decisions, there are a lot of individual points where things can go wrong. Going wrong can have multiple meanings here: this can range from routing loops, causing Internet traffic to go back and forth repeatedly between two networks, never reaching its destination, to more malicious problems, such as traffic interception or traffic manipulation.
As routing security wasn’t accounted for in that initial two-napkin draft, it is easy for a malicious actor on the Internet to pretend to either be an originating network (where they claim to own the IP prefix, positioning themselves as the destination network), or they can pretend to be a viable middle network, getting traffic to transit through their network.
In either of these examples, the actor can manipulate the Internet traffic of unsuspecting end users and potentially steal passwords, cryptocurrency, or any other data that can be of value. While transport security (TLS for HTTP/1.x and HTTP/2, QUIC for HTTP/3) has reduced this risk significantly, there’s still ways this can be bypassed. Over time, the Internet community has acknowledged the security concerns with BGP, and has built infrastructure to mitigate some of these problems.
BGP security: The RPKI is born
This journey is now coming to a final destination with the development and adoption of the Resource Public Key Infrastructure (RPKI). The RPKI is a PKI, just like the Web PKI which provides security certificates for the websites we browse (the “s” in https). The RPKI is a PKI specifically with the Internet in mind: it provides core constructs for IP addresses and Autonomous System Numbers (ASNs), the numbers used to identify these individual operating networks mentioned earlier.
Through the RPKI, it’s possible for an operator to establish a cryptographically secure relationship between the IP prefixes they originate, and their ASN, through the issuance of Route Origin Authorization records (ROAs). These ROAs can be used by all other networks on the Internet to validate that the IP prefix update they just received for a given origin network actually belongs to that origin network, a process called Route Origin Validation (ROV). If a malicious party tries to hijack an IP prefix that has a ROA to their (different) origin network, validating networks would know this update is invalid and reject it, maintaining the origin security and ensuring reachability.
Why does BGP security matter? Examples of route hijacks and leaks
But why should you care about BGP? And more importantly, why does the White House care about BGP? Put simply: BGP (in)security can cost people and companies millions of dollars and cause widespread disruptions for critical services.
In February 2022, Korean crypto platform KLAYswap was the target of a malicious BGP hijack, which was used to steal $1.9 million of cryptocurrency from their customers. The attackers were able to serve malicious code that mimicked the service KLAYswap was using for technical support. They were able to do this by announcing the IP prefix used to serve the JavaScript SDK KLAYswap was using. When other networks accepted this announcement, end user traffic loading the technical support page instead received malicious JavaScript, which was used to drain customer wallets. As the attackers hijacked the IP address, they were also able to register a TLS certificate for the domain name used to serve the SDK. As a result, nothing looked out of the ordinary for Klayswap’s customers until they noticed their wallets had been drained.
However, not all BGP problems are intentional hijacks. In March 2022, RTComm (AS8342), a Russian ISP, announced itself as the origin of 104.244.42.0/24, which is an IP prefix actually owned by Twitter (now X) (AS13414). In this case, all researchers have drawn a similar conclusion: RTComm wanted to block its users from accessing Twitter, but inadvertently advertised the route to its peers and upstream providers. Thankfully, the impact was limited, in large part due to Twitter issuing ROA records for their IP prefixes, which meant the hijack was blocked at all networks that had implemented ROV and were validating announcements.
Inadvertent incorrect advertisements passing from one network to another, or route leaks, can happen to anyone, even Cloudflare. Our 1.1.1.1 public DNS service — used by millions of consumers and businesses — is often the unintended victim. Consider this situation (versions of which have happened numerous times): a network engineer running a local ISP is testing a configuration on their router and announces to the Internet that you can reach the IP address 1.1.1.1 through their network. They will often pick this address because it’s easy to input on the router and observe in network analytics. They accidentally push that change out to all their peer networks — the networks they’re connected to — and now, if proper routing security isn’t in place, users on multiple networks around the Internet trying to reach 1.1.1.1 might be directed to this local ISP where there is no DNS service to be found. This can lead to widespread outages.
The types of routing security measures in the White House roadmap can prevent these issues. In the case of 1.1.1.1, Cloudflare has ROAs in place that tell the Internet that we originate the IP prefix that contains 1.1.1.1. If someone else on the Internet is advertising 1.1.1.1, that’s an invalid route, and other networks should stop accepting it. In the case of KLAYswap, had there been ROAs in place, other networks could have used common filtering techniques to filter out the routes pointing to the attackers malicious JavaScript. So now let’s talk more about the plan the White House has to improve routing security on the Internet, and how the US government developed its recommendations.
Cloudflare first started publicly advocating for adoption of security measures like RPKI after a massive BGP route leak took down a portion of the Internet, including websites using Cloudflare’s services, in 2019.
Since that time, the federal government has increasingly recognized the need to elevate efforts to secure Internet routing, a process that Cloudflare has helped support along the way. The Cyberspace Solarium Commission report, published in 2020, encouraged the government to develop a strategy and recommendations to define “common, implementable guidance for securing the DNS and BGP.”
In February 2022, the Federal Communication Commission launched a notice of inquiry to better understand Internet routing. Cloudflare responded with a detailed explanation of our history with RPKI and routing security. In July 2023, the FCC, jointly with the Director of the Cybersecurity and Infrastructure Security Agency, held a workshop for stakeholders, with Cloudflare as one of the presenters. In June 2024, the FCC issued a Notice of Proposed Rulemaking that would require large service providers to develop security risk management plans and report on routing security efforts, including RPKI adoption.
The White House has been involved as well. In March 2023, they cited the need to secure the technical foundation of the Internet, from issued such as BGP vulnerabilities, as one of the strategic objectives of the National Cybersecurity Strategy. Citing those efforts, in May 2024, the Department of Commerce issuedROAs signing some of its IP space, and this roadmap strongly encourages other departments and agencies to do the same. All of those efforts and the focus on routing security have resulted in increased adoption of routing security measures.
Report observations and recommendations
The report released by the White House Office of the National Cyber Director details the current state of BGP security, and the challenges associated with Resource Public Key Infrastructure (RPKI) Route Origin Authorization (ROA) issuance and RPKI Route Origin Validation (ROV) adoption. It also provides network operators and government agencies with next steps and recommendations for BGP security initiatives.
One of the first recommendations is for all networks to create and publish ROAs. It’s important that every network issues ROAs for their IP prefixes, as it’s the only way for other networks to validate they are the authorized originator of those prefixes. If one network is advertising an IP address as their own, but a different network issued the ROA, that’s an important sign that something might be wrong!
As shown in the chart below from NIST’s RPKI Monitor, as of September 2024, at least 53% of all the IPv4 prefixes on the Internet have a valid ROA record available (IPv6 reached this milestone in late 2023), up from only 6% in 2017. (The metric is even better when measured as a percent of Internet traffic: data from Kentik, a network observability company, shows that 70.3% of Internet traffic is exchanged with IP prefixes that have a valid ROA.) This increase in the number of signed IP prefixes (ROAs) is foundational to secure Internet routing.
Unfortunately, the US is lagging behind: Only 39% of IP prefixes originated by US networks have a valid ROA. This is not surprising, considering the US has significantly more Internet address resources than other parts of the world. However, the report highlights the need for the US to overcome the common barriers network operators face when implementing BGP security measures. Administrative challenges, the perception of risk, and prioritization and resourcing constraints are often cited as the problems networks face when attempting to move forward with ROV and RPKI.
A related area of the roadmap highlights the need for networks that allow their customers to control IP address space to still create ROAs for those addresses. The reality of how every ISP, government, and large business allocates its IP address space is undoubtedly messy, but that doesn’t reduce the importance of making sure that the correct entity is identified in the official records with a ROA.
A network signing routes for its IP addresses is an important step, but it isn’t enough. To prevent incorrect routes — malicious or not — from spreading around the Internet, networks need to implement Route Origin Validation (ROV) and implement other BGP best practices, outlined by MANRS in their Zen Guide to Routing Security Policy. If one network incorrectly announces itself as the origin for 1.1.1.1, that won’t have any effect beyond its own borders if no other networks pick up that invalid route. The Roadmap calls out filtering invalid routes as another action for network service providers.
As of 2022, our data showed that around 15 percent of networks were validating routes. Ongoing measurements from APNIC show progress: this year about 20 percent of APNIC probes globally correctly filter invalid routes with ROV. In the US, it’s 70 percent. Continued growth of ROV is a critical step towards achieving better BGP security.
Filtering out invalid routes is prominently highlighted in the report’s recommendations. While recognizing that there’s been dramatic improvement in filtering by the large transit networks, the first report recommendation is for network service providers — large and small — to fully deploy ROV.
In addition, the Roadmap proposes using the federal government’s considerable weight as a purchaser, writing, “[Office of Management and Budget] should require the Federal Government’s contracted service providers to adopt and deploy current commercially-viable Internet routing security technologies.” It goes on to say that grant programs, particularly broadband grants, “should require grant recipients to incorporate routing security measures into their projects.”
The roadmap doesn’t only cover well-established best practices, but also highlights emerging security technologies, such as Autonomous System Provider Authorization (ASPA) and BGPsec. ROAs only cover part of the BGP routing ecosystem, so additional work is needed to ensure we secure everything. It’s encouraging to see the work being done by the wider community to address these concerns is acknowledged, and more importantly, actively followed.
What’s next for the Internet community
The new roadmap is an important step in outlining actions that can be taken today to improve routing security. But as the roadmap itself recognizes, there’s more work to be done both in making sure that the steps are implemented, and that we continue to push routing security forward.
From an implementation standpoint, our hope is that the government’s focus on routing security through all the levers outlined in the roadmap will speed up ROA adoption, and encourage wider implementation of ROV and other best practices. At Cloudflare, we’ll continue to report on routing practices on Cloudflare Radar to help assess progress against the goals in the roadmap.
At a technical level, the wider Internet community has made massive strides in adopting RPKI ROV, and have set their sights on the next problem: we are securing the IP-to-originating network relationship, but what about the relationships between the individual networks?
Through the adoption of BGPsec and ASPA, network operators are able to not only validate the destination of a prefix, but also validate the path to get there. These two new technical additions within the RPKI will combine with ROV to ultimately provide a fully secure signaling protocol for the modern Internet. The community has actively undertaken this work, and we’re excited to see it progress!
If you’re a network operator, you’ll need to sign your routes, and validate incoming prefixes. This consists of signing Route Origin Authorization (ROA) records, and performing Route Origin Validation (ROV). Route signing involves creating records with your local Regional Internet Registry (RIR) and signing to their PKI. Route validation involves only accepting routes that are signed with a ROA. This will help ensure that only secure routes get through. You can learn more about that here.
If you’re not a network operator, head to isbgpsafeyet.com, and test your ISP. If your ISP is not keeping BGP safe, be sure to let them know how important it is. If the government has pointed out prioritization is a consistent problem, let’s help increase the priority of routing security.
A secure Internet is an open Internet
As the report points out, one of the keys to keeping the Internet open is ensuring that users can feel safe accessing any site they need to without worrying about attacks that they can’t control. Cloudflare wholeheartedly supports the US government’s efforts to bolster routing security around the world and is eager to work to ensure that we can help create a safe, open Internet for every user.

At this year’s GUADEC in Denver, Colorado, Behdad Esfahbod and Matthias Clasen
presented a two-part talk on a topic that’s deeply important to desktop
environments: fonts. Esfahbod covered advances in font
technology that are making their way to becoming standards, and Clasen briefly
discussed improvements in GTK text rendering. The talk presented some
fascinating insights into the problems around accurately rendering
writing systems on the desktop, and where font technologies may be
going in the near future.
Security updates have been issued by AlmaLinux (postgresql:16), Debian (dovecot, pymatgen, ruby2.7, systemd, and webkit2gtk), Fedora (microcode_ctl, python3.11, vim, and xen), Oracle (kernel, postgresql:12, postgresql:13, postgresql:15, and python39:3.9 and python39-devel:3.9), Slackware (libpcap), SUSE (cacti, cacti-spine, python-Django, and trivy), and Ubuntu (dovecot).
…a special lane at airport security called Known Crewmember (KCM). KCM is a TSA program that allows pilots and flight attendants to bypass security screening, even when flying on domestic personal trips.
The KCM process is fairly simple: the employee uses the dedicated lane and presents their KCM barcode or provides the TSA agent their employee number and airline. Various forms of ID need to be presented while the TSA agent’s laptop verifies the employment status with the airline. If successful, the employee can access the sterile area without any screening at all.
A similar system also exists for cockpit access, called the Cockpit Access Security System (CASS). Most aircraft have at least one jumpseat inside the cockpit sitting behind the flying pilots. When pilots need to commute or travel, it is not always possible for them to occupy a revenue seat, so a jumpseat can be used instead. CASS allows the gate agent of a flight to verify that the jumpseater is an authorized pilot. The gate agent can then inform the crew of the flight that the jumpseater was authenticated by CASS.
[attack details omitted]
At this point, we realized we had discovered a very serious problem. Anyone with basic knowledge of SQL injection could login to this site and add anyone they wanted to KCM and CASS, allowing themselves to both skip security screening and then access the cockpits of commercial airliners.
We ended up finding several more serious issues but began the disclosure process immediately after finding the first issue.
Linus has released 6.11-rc6 for testing.
“Things look pretty normal, although we have perhaps unusually many
filesystem fixes here, spread out over smb, xfs, bcachefs and netfs.“
По принцип видеото ми е един от най-бавните и неудобни начини да приемам информация (това въпреки всичкото време, което съм отделил за записване и stream-ване на конференции). Та рядко гледам такива неща, и много често предпочитам да си прочета за нещо, вместо да седя и да слушам.
Тия дни обаче попаднах на запис на лекция на Grace Hopper в NSA, който наскоро са разсекретили (и в който няма нищо особено секретно или тайно). За лекция, която е изнесена преди 30-40 години, нещата са доста интересни и на място, доста от проблемите от тогава съществуват и сега, а самият разказ и начинът на разказване са едни от най-добрите, дето съм виждал.
Та, препоръчвам.
