As organizations increasingly embrace remote working and remotely-monitored industrial operations, newfound gaps in the network’s cyber security preparedness become apparent. In fact, more use of cloud-hosted remote apps, services and resources – for all the useful and convenient accessibility they bring – can also further expose company systems and assets to a wider cyber threat landscape. The cyber protection programs of many organizations were configured for on-premise protection, but many of the newer tools and services in production are cloud-based. Hence a lot of on-premise cybersecurity solutions that were cutting-edge and capable of company-wide protection when they were first installed, are now outmoded in the face of an ever-evolving threat surface that can’t be secured just by shielding endpoints. Today the cyber challenges threaten an organization on many fronts, and the advent and rapid adoption of cloud solutions (often from different service providers that offer the best toolset for specific needs) has created multiple-threat zones that are difficult to compartmentalize and therefore identify cases of malicious activity. The threat variety is extremely diverse and multi-shaded. Security lapses might include data breaches, broken authentication and account hijacking — while some activities may not seem particularly threatening, but are signs that the enterprise is being “scoped” in ways that don’t necessarily raise red flags when regarded in isolation. At stake is the organization’s data, and (typically) from that data, monetary gain. But reputational damage alone can cripple some companies, especially in sensitive verticals. Once compromised, it might be possible to recover original data or be assured that the data loss was not game-changing. But if malicious actors were to capture data...
Penetration testing is becoming increasingly common as organizations are starting to embrace the requirement for stronger cybersecurity. But there are yet too many businesses that don’t understand the benefits of regular security testing. Penetration testing is vital for any kind of organization with an IT system or website. A recent survey of penetration testers reported that 88 percent of those questioned stated they could infiltrate companies and steal data within 12 hours. This explains that almost all businesses are likely to be exposed to attacks. But many people do not know what a Penetration test includes particularly the types of vulnerabilities that testing benefits to identify. In truth, there are many various types of Penetration testing, and the results can depend mainly on which type you have carried. What Is A Penetration Test? A penetration test comprises a team of security professionals who actively try to break into your company’s network by using weaknesses and vulnerabilities in your systems. Penetration tests may involve any of the following purposes: Using social engineering techniques to enter systems and related databases. Sending of phishing emails to reach critical accounts. Using unencrypted passwords distributed in the network to reach sensitive databases. These attempts can be very intrusive than a vulnerability scan and may cause a rejection of service or increased system utilization, which may decrease productivity, and damage the machines. In some instances, you may schedule penetration tests and notify staff in advance of the exercise. However, this wouldn’t be suitable if you want to examine how your internal security team reacts to a “live” threat. A penetration test can decide if certain...
After talking to machine learning and infrastructure engineers at major Internet companies across the US, Europe, and China, I noticed two groups of companies. One group has made significant investments (hundreds of millions of dollars) into infrastructure to allow real-time machine learning and has already seen returns on their investments. Another group still wonders if there’s value in real-time ML. There seems to be little consensus on what real-time ML means, and there hasn’t been a lot of in-depth discussion on how it’s done in the industry. In this post, I want to share what I’ve learned after talking to about a dozen companies that are doing it. There are two levels of real-time machine learning that I’ll go over in this post. Level 1: Your ML system makes predictions in real-time (online predictions). Level 2: Your system can incorporate new data and update your model in real-time (incremental learning). I use “model” to refer to the machine learning model and “system” to refer to the infrastructure around it, including data pipeline and monitoring systems. Table of contents ….

A NSW government-sponsored taskforce of industry leaders has called on federal, state and local governments across Australia to adopt internationally recognised cyber security standards for cloud services. It has also urged governments to more favourably evaluate proposals or tender bids from companies that adopt cyber security and other risk standards for telecommunications and the Internet of Things (IoT). The NSW cyber security standards harmonisation taskforce made the recommendations alongside 22 others in a 16-page report [pdf] released on Thursday. It follows six-months of work by the taskforce – which consists of representatives from across the defence, energy health and financial services sectors – to drive the adoption of standards. The report separates recommendations for standards development and implementation into seven key areas: cloud, defence, education, energy, financial services, health and telco and IoT. The taskforce found that there was generally a myriad of cyber security standards to select from, with some embedded into policy and others not. In the cloud arena, the report urges governments to “adopt and leverage recognised ISO and/or IEC standards as baseline requirements for information security (i.e. ISO/IEC 27000 series)”. Governments looking to introduce new cloud services at a protected level or below should also consider “ISO/IEC 27001, SOC 2 and potentially FedRAMP as part of a uniform security baseline”. ISO/IEC 27000 is a widely-known family of standards used to ensure information assets are secure, whereas FedRamp is a US program providing a standardised approach to cloud security assessments. The report said that standards could be embedded within “any regulatory frameworks or procurement models proposed in relation to cyber security”. Governments have similarly been urged to adopt...
2020’s SolarWinds cyberattack, which affected numerous US government agencies, underscores the growing relevance of IT security and cyber-crime to national governments. Not solely the work of individual criminals, crimes perpetrated by state-sponsored or entirely state-operated hacker groups have increasingly been alleged. With cyberspace growing in importance as a frontier of political contestation, states must act; what steps has Japan been taking, and what barriers are there to enhancing Japan’s cybersecurity? The SolarWinds hack involved a group of hackers, , sneaking malicious code into the update system of the SolarWinds IT management software. Compromised updates were then downloaded by the software’s users, which range from . As a result, the hackers likely gained access to data critical to economic competitiveness and national security. This incident underlines the risk posed by cyberattacks that use non-state vectors to their advantage. Though Japan does not seem to have become a significant victim of the SolarWinds hack, its current state cybersecurity strategy is vulnerable to a similar attack due to weaknesses in areas such as its funding and focus. Japan’s Cyber Security Forces Today At the time of writing, the Japan Self-Defence Force (JSDF) operates a Cyber Defence Group of 290 personnel under the control of the SDF’s Command Control Communication Computers Systems Command (C4SC). Combined with cyber defence personnel already under the umbrella of the C4SC, Japan has approximately dedicated to cyber security for the JSDF as a whole. It is worth noting that each branch of the JSDF (ground, air and maritime) has its own dedicated cyber defence unit; these units combined total around 370 personnel. There also exists a small of...
Escherichia coli bacteria can convert electrical pulses into bits of DNA stored in their genome. Scientists ‘program’ living bacteria to store data By Robert F. ServiceJan. 11, 2021 , 1:35 PM Hard disks and optical drives store gigabits of digital data at the press of a button. But those technologies—like the magnetic tapes and floppy drives before them—are apt to become antiquated and unreadable when they are overtaken by new technology. Now, researchers have come up with a way to electronically write data into the DNA of living bacteria, a storage option unlikely to go obsolete any time soon. “This is a really nice step” that might one day spur commercial development, says Seth Shipman, a bioengineer at the Gladstone Institutes and the University of California, San Francisco, who was not involved in the new work. He notes, however, that real-world applications are a long way off. DNA is attractive for data storage for several reasons. First, it is more than 1000 times as dense as the most compact hard drives, enabling it to store the equivalent of 10 full-length digital movies within the volume of a grain of salt. And because DNA is central to biology, the technologies to read and write it are expected to become cheaper and more powerful with time. Storing data in DNA is not a new idea. To do so, researchers typically convert a data file’s string of digital ones and zeros into combinations of the molecule’s four bases: adenine, guanine, cytosine, and thymine. They then use a DNA synthesizer to write that code into DNA. But the accuracy of DNA synthesis decreases the...
