Self-supervised learning (SSL) allows us to train a system to learn good representation of the inputs in a task-independent way. Because SSL training uses unlabeled data, we can use very large training sets, and get the system to learn more robust and more complete representations of the inputs. It then takes a small amount of labeled data to get good performance on any supervised task. This greatly reduces the necessary amount of labeled data [endemic to] pure supervised learning, and makes the system more robust, and more able to handle inputs that are different from the labeled training samples. It also sometimes reduces the sensitivity of the system to bias in the data—an improvement about which we’ll share more of our insights in research to be made public in the coming weeks. What’s happening now in practical AI systems is that we are moving toward larger architectures that are pretrained with SSL on large amounts of unlabeled data. These can be used for a wide variety of tasks. For example, Meta AI now has language-translation systems that can handle a couple hundred languages.
In the rush to keep operations going, many businesses made quick decisions and often, adopted the wrong services for their organisation. Our own research found that over half (53%) of UK IT decision makers believe they made unnecessary tech investments during the Covid-19 pandemic, and by speeding up or ignoring their original strategy, have hindered their long term resilience. One thing almost all businesses have recognised throughout the pandemic, is that their people are the most critical and limiting factor to their business. Employee time is valuable and by not having technology that supports them in their role, productivity will drop, and employees may become an internal threat in terms of cyber security. If businesses acknowledge that hybrid is the new normal, and their people should be the priority, they can go some way to understand how IT moves from an expense to adding value. Although most of this has stemmed from a pandemic no one could have predicted, businesses and their leaders must now make sure they haven’t created the perfect storm of a distributed, disconnected workforce that is at risk of service outages.
The attacks employing the Bvp47 backdoor are dubbed as 'Operation Telescreen' by Pangu Lab. A telescreen was a device envisioned by George Orwell in his novel 1984 that enabled the state to remotely monitor others to control them. According to Pangu Lab researchers, the malicious code of Bvp47 was developed to give operators long-term control over compromised machines. 'The tool is well-designed, powerful, and widely adapted. Its network attack capability equipped by 0-day vulnerabilities was unstoppable, and its data acquisition under covert control was with little effort,' they said. Complex code, Linux multi-version platform adaption, segment encryption and decryption and extensive rootkit anti-tracking mechanisms are all part of Bvp47's implementation. It also features an advanced BPF engine, which is employed in advanced covert channels, as well as a communication encryption and decryption procedure. The researchers say the attribution to the Equation Group is based on the fact the sample code shows similarities with exploits contained in the encrypted archive file 'eqgrp-auction-file.tar.xz.gpg' which was posted by the Shadow Brokers after the failed auction in 2016.
Cloud computing is the process of delivering on-demand services or resources over the internet that allows users to gain seamless access to resources from remote locations without expending any additional time, cost or workforce. Switching from building in-house data centres to cloud computing helps the company reduce its investment and maintenance costs considerably. ... Fog computing is a type of computing architecture that utilises a series of nodes to receive and process data from IoT devices in real-time. It is a decentralised infrastructure that provides access to the entry points of various service providers to compute, store, transmit and process data over a networking area. This method significantly improves the efficiency of the process as the time utilised in the transmission and processing of data is reduced. In addition, the implementation of protocol gateways ensures that the data is secure. ... Cloud or fog data prove to be unreliable when dealing with applications that require instantaneous responses with tightly managed latency. Edge computing deals with processing persistent data situated near the data source in a region considered the ‘edge’ of the apparatus.
One of the promises of a decentralized Web3 is the notion that as users we can all own our data. This is in contrast to Web 2.0, where the prevailing view is that we the users and our data are the product being exploited for financial gain by large centralized organizations. A data union is a scalable way to collect real-time data from individuals and package that data for sale, in a way that is mutually agreeable to both the data source and the packaging application. Much like workers joining a union in real life to rally around a common set of goals, data unions allow individuals to join these unions to aggregate data in a controlled way, complete with the ability to vote on how and where the data is used, through DAO (decentralized autonomous organization) governance. For users, one challenge to the idea of controlling your data is finding an interested buyer. Few data consumers want to go through the hassle of acquiring data from one individual at a time. Data unions solve this by aggregating data from a set of users who opt-in.
In terms of the impact of this vulnerability, Apiiro has determined the following (so far). Note that the following information was from Apiiro’s website at the time of the announcement and may be subject to change. Please refer to Apiiro’s website for the latest information. Here’s what we know about the vulnerability and what it could enable an attacker: The attacker can read and exfiltrate secrets, tokens, and other sensitive information residing on other applications; The attacker can “move laterally” from their application to another application’s data. The risk was given a severity rating of high given that the malicious Helm chart could potentially expose sensitive information stored on a Git repository and also “roam” through applications allowing attackers to read secrets, tokens, and sensitive data that reside within the applications. The team behind Argo CD quickly provided a patch that impacted organizations should apply as soon as possible as the vulnerability affects all versions of the tool. The patch is available via Argo CD’s GitHub repository.
In order to achieve shorter-term automation goals, businesses need to evaluate their existing automation needs and ask a few key questions. Are they seeking to automate mundane tasks to increase personal productivity, such as processing emails, setting up notifications or organising files? Personal productivity automation is employee-driven and used to tackle multiple tasks for productivity gains at the individual level. Are they seeking to streamline business processes, such as processing a high volume of invoices or moving data from one system to another? Business process automation (BPA) is also employee-driven but it streamlines business processes to deliver efficiencies and productivity gains across users and departments. Automation might also be an ongoing project, often referred to as an automation Centre of Excellence (CoE), which focuses on intricate, enterprise-wide automation and orchestration. CoE-driven automation is fairly complicated and has a significant influence on automating connected processes.
Independent work-streams allowed them to work in parallel. Does that mean we did not have any dependencies? Not really. We had a stand-up which we called as Scrum of Scrum, conducted daily, with participation from each development team, with focus on dependencies and impediment resolution during the iteration. Given the nature of program and diverse set of stakeholders, we decided to conduct consolidated program iteration planning and showcase events. Development teams would conduct their planning meetings individually. And join this program meeting to share summary of key features taken up in the iteration, and the sprint goal. Lastly, to provide stakeholders a view of how we were progressing against defined release milestones, we tracked progress against iteration goals vis-à-vis release objectives. A release was defined as a set of features required to board users from a specific Geography. We provided a one-page weekly/fortnightly program summary to senior CIO leadership and program stakeholders, with data from ALM tool, along with any blockers & issues that needed executive leadership support.
While the clauses were issued in the company’s marketing association bulletin and allowed individual underwriters flexibility in applying them to individual policies, they were widely interpreted as signifying a shift toward non-coverage. All of Lloyd’s cyber policies are expected to include some variation of these clauses going forward. Lloyd's of London's definition of cyberwar broadly includes “cyber operations between states which are not excluded by the definition of war, cyber war or cyber operations which have a major detrimental impact on a state.” Formal attribution is not necessary for exclusion, an important caveat that would allow for broad latitude in making determinations of whether a given event is actually cyberwar or not. “I think you're going to see a lot more of that, unless there is legislation that comes out that more specifically defines cyberwar. I don't think we're really seeing it at this point,” notes Adrian Mak, CEO of AdvisorSmith. The language in the individual contracts is “what is driving the coverage at this point. And also, interpretation of that [language].”
Fear is a natural reaction when we enter uncharted territory. Moreover, the digital transformation journey also requires skill, patience, and a huge financial investment, which adds an extra level of anxiety. Many leaders are uncertain about investing resources into an initiative that they are unsure of, even if there are plenty of stats available to back it up. If you are feeling uncomfortable, try to focus your energy toward embracing your digital transformation initiative and giving it everything it needs to succeed. Remind yourself that in time, you will witness the positive results of your efforts and even scale your business’s revenue. Every enterprise and organization must eventually make digitalization a strategic cornerstone to remain competitive and better serve their constituents. If convenience, scalability, and security are among your business priorities, implementing a thoughtful digital transformation initiative is essential.
