The essence of information privacy is control over disclosure. Whoever is responsible for the information is supposed to be able to decide who sees it. If a society values privacy, it needs to ensure that there are reasonable protections possible against disclosure to those not authorized by the information's owner. In the online world, an essential technical component for this assurance is encryption. If the encryption that is deployed permits disclosure to those who were not authorized by the information's owner, there should be serious concern about the degree of privacy that is meaningfully possible. more
It seems like the online Russian population is getting mobilized. Like a meme spreading on the blogosphere, the mob is forming and starting to "riot", attacking Georgia. This seems very similar to the Estonian incident, only my current guess is natural evolution rather than grass-roots implanted -- but I am getting more and more convinced of the similarities as more information becomes available. Determining exactly when the use of scripts by regular users started, is key to this determination. more
When it comes to fighting cybercrime, "being able to easily access ICANN and look up IP addresses is a lot more important than accessing the minutiae of encrypted data communications," says Jacqueline McNamara, head of cybersecurity at Telstra. more
If the rise of phishing has taught us anything, it's that on the Internet, if a digital asset has value, there's somebody out there who wants to steal it. Whether it's a bank account password, a credit card number, a PayPal login, or even a magic sword in an online game, there's a fraudster somewhere trying to misappropriate it for his or her own nefarious purposes. Domain names have always been a target for such criminals. more
Are file inclusion vulnerabilitiess equivalent to remote code execution? Are servers (both Linux and Windows) now the lower hanging fruit rather than desktop systems? In the February edition of the Virus Bulletin magazine, we (Kfir Damari, Noam Rathaus and Gadi Evron (me) of Beyond Security) wrote an article on cross platform web server malware and their massive use as botnets, spam bots and generally as attack platforms. Web security papers deal mostly with secure coding and application security. In this paper we describe how these are taken to the next level with live attacks and operational problems service providers deal with daily. more
One of the most striking and enduring dichotomies in the conceptualization of electronic communication networks is summed up in the phrase "the Internet as weapon." With each passing day, it seems that the strident divergence plays in the press -- the latest being Tim's lament about his "web" vision being somehow perverted. The irony is that the three challenges he identified would have been better met if he had instead pursued a career at the Little Theatre of Geneva and let SGML proceed to be implemented on OSI internets rather than refactoring it as HTML to run on DARPA internets. more
Coninsiding with October Cybersecurity Awareness Month, Google today announced the launch of Advanced Protection Program specifically "designed for those who are at an elevated risk of attack." more
"Three years after Mirai first appeared, and two years after WannaCry, it shows that we still haven't solved the problems leveraged in those outbreaks," said F-Secure Principal Researcher Jarno Niemela. more
In light of increasing reports of malicious activity targeting the DNS infrastructure, ICANN is calling for the full deployment of the Domain Name System Security Extensions (DNSSEC) across all unsecured domain names. more
Distributed Denial of Service is a big deal -- huge pools of Internet of Things (IoT) devices, such as security cameras, are compromised by botnets and being used for large scale DDoS attacks. What are the tools in hand to fend these attacks off? The first misconception is that you can actually fend off a DDoS attack. There is no magical tool you can deploy that will allow you to go to sleep every night thinking, "tonight my network will not be impacted by a DDoS attack." more
The African Union's Convention on the Establishment of a Credible Legal Framework for Cyber Security in Africa (AUCC) has been the focus of debate recently.To shed light on online security issues in Africa, CIO East Africa sought the views of Ms Sophia Bekele, an internet security expert and international policy advisor over internet and ICT. more
In this multipart series I will be presenting some of the leading industry-standard best practices for enterprise network security using Cisco technologies. Each article in the series will cover a different aspect of security technologies and designs and how each can be deployed in the enterprise to provide the best security posture at the lowest possible budgetary and administrative cost. In Part 2 of this series I discussed security risks and vulnerability. In this article we begin to focus on the role Cisco network and security technologies play in ensuring the safety and security of network data. more
Denial of service attacks have been around since the Internet was commercialized and some of the largest attacks ever launched relied on DNS, making headlines. But every day a barrage of smaller DNS-based attacks take down targets and severely stress the DNS ecosystem. Although DNS servers are not usually the target of attacks they are often disrupted so attention from operation teams is required. There is no indication the problem is going away and attackers continue to innovate. more
Unlike traditional attacks by hackers which breach a business's security systems, resulting in defaced websites, intellectual property theft and/or customer data theft, a DDoS attack focuses on making a business's Internet connected infrastructure (e.g. web servers, email servers, database servers, FTP servers, APIs, etc.) unavailable to legitimate users. A business's brand reputation, which can take years to establish, can be swept away in just a few hours from a single DDoS attack in the same way a natural disaster like a flood or earthquake can impact a traditional brick and mortar business. more
There's been a lot of media attention to a report that iPhones track your movements. It's even reached the U.S. Senate. I'm underwhelmed. I think that the threat is overhyped. What is happening is that these devices create a hidden file with your location... more
