IP Address Blocking

A network can fence its own IP addresses or block specific external ones from access. Administrators frequently block access to their own IP addresses to bar unwanted access to content. Individual IPs or blocks of IPs may also be blocked due to unwanted or malicious behavior. IP address blocking prevents a specific IP address or group of IP addresses from connecting with a server, computer, or application. more

Dissecting the 2022 UK Cyber Security Strategy: The ‘Whole of Society’ Approach

The UK government launched its 2022 Cyber Security Strategy on 15 December 2021, outlining its ambitious plans to improve the resilience of UK institutions and businesses while protecting the country's interests in cyberspace. The strategy signals a more involved approach by the government, which previously relied heavily on the private sector for leadership. The government's stated commitment to a 'whole of society' approach sounds really good on paper, but what exactly does it really mean? more

DNSSEC Adoption Part 3: A Five Day Hole in Online Security

Implementing security requires attention to detail. Integrating security services with applications where neither the security service nor the application consider their counterpart in their design sometimes make plain that a fundamental change in existing practices is needed. Existing "standard" registrar business practices require revision before the benefits of the secure infrastructure foundation DNSSEC offers can be realized. more

Richard Clarke: Defend Against Cyberwar by Re-Architecting Networks, Not Buying More Technology

In his keynote yesterday at the RSA Security Conference, former U.S. top chief counter-terrorism adviser, Richard A. Clarke, said cyberwar defence efforts need to focus on re-architecting networks not buying more technology. more

60 Minutes Investigates Cybersecurity and the Reality of Sabotaging Critical Infrastructure

CBS's 60 Minutes aired a special report last night investigating how hackers can get into the computer systems that run crucial elements of the world's infrastructure, such as the power grids, water works or even a nation's military arsenal. From the report: "At the Sandia National Laboratories, Department of Energy security specialists like John Mulder try to hack into computer systems of power and water companies, and other sensitive targets in order to figure out the best way to sabotage them. It's all done with the companies' permission in order to identify vulnerabilities. In one test, they simulated how they could have destroyed an oil refinery by sending out code that caused a crucial component to overheat." more

Video: Highlights of the DNSSEC Key Signing Ceremony

ICANN video highlighting last week's historical DNSSEC key signing ceremony held in a high security data centre located in Culpeper, VA, outside of Washington, DC. "During the ceremony, participants were present within a secure facility and witnessed the preparations required to ensure that the so-called key-signing-key (KSK) was not only generated correctly, but that almost every aspect of the equipment, software and procedures associated with its generation were also verified to be correct and trustworthy." more

DNSSEC vs DDoS Protection: Is It Really a Choice?

Within the last year or two, I've heard people express an opinion to the effect that if the domain name industry put as much focus on preventing distributed denial of service attacks as we have on implementing DNSSEC, the Internet would be a safer place. While there may be a grain of truth there, I suggest that this kind of thinking presents us with something of a false dichotomy. more

ICANN Begins Public DNSSEC Test Plan for the Root Zone

The deployment of Domain Name System Security Extensions (DNSSEC) for the root zone got an official start today with its public signing for the first time. DNSSEC for the root zone is a joint effort between ICANN and VeriSign, with support from the U.S. Department of Commerce to improve security of the Internet's naming infrastructure. Kim Davies, ICANN's Manager of Root Zone Services, says: "What happened today was the deliberately un-validatable root zone started being published on l.root-servers.net. It is anticipated this will be rolled out across the other root servers over the coming months. This phase is designed to identify any issues with the larger DNS response sizes associated with DNSSEC data." more

2012 Security Predictions: APT’s, Mobile Malware and Botnet Takedowns

As the weeks remaining in 2011 dwindle and 2012 peaks out from behind the last page of the calendar, it must once again be that time of year for purposeful reflection and prediction. Or is that navel gazing and star gazing? At the highest level of navel gazing you could probably sum up 2011 with one word -- "More"... But let's put that aside for now. What does 2012 hold in stall for us? more

ICANN Facing Critical Choice for Plan to Change DNS Cryptographic Key

While the majority of ICANN's Security and Stability Advisory Committee (SSAC) have given the organization the green signal to roll, or change, the "top" pair of cryptographic keys used in the DNSSEC protocol, commonly known as the Root Zone KSK (Key Signing Key), five members of the committee advised against the October 11 rollover timeline. more
