Getting into cybersecurity: Self‑taught vs. university‑educated? – 10 minute mail

Are you considering a career in cybersecurity? What learning path(s) should you take? Does formal education matter? ESET experts share their insights.

With cyberthreats on the rise, cybersecurity professionals are, unsurprisingly, a hot commodity. According to a recent study by Cybersecurity Ventures, there will be 350% growth in open cybersecurity positions from 2013 to 2021 and it is estimated that, due to the talent crunch, there will be 3.5 million job openings in the industry by 2021.

With that in mind, one of our articles to mark this year’s Antimalware Day features insights from several ESET security researchers. We asked them a series of questions to learn how they built their expertise and to gather their thoughts about the usefulness of formal education versus self-study for becoming a security practitioner.

Learn all by yourself?

While more and more colleges and universities worldwide offer degree programs in computer security, far from all academic institutions have launched such programs. Indeed, many experts in the field are self-taught and/or have acquired their skills through various non-academic courses and certifications.

ESET Distinguished Researcher Aryeh Goretsky, who embarked on a career in IT security in the late 1980s, notes that back then there weren’t actually any courses or certifications specifically focused on computer security.

“Computer security was taught, but it was largely in terms of models for access control, and I think tended to focus more on the concept of securing multiple-user computer systems and users’ access to them being seen as more of an atomic model than as bits and pieces of a larger, more globally-interconnected system. So, the people who were interested in the concept of cybersecurity, of how disparate computers and networks might behave towards each other, kind of had to self-teach. Some of that might come from reading standard computer science and engineering and reference tomes, and learning about computer and network operations, but some of that knowledge came from… shall we say, unofficial and very hands-on experimentation,” he explains.

This is echoed by Marc-Etienne M.Léveillé, a malware researcher at ESET’s lab in Canada who studied software development and computer engineering. “The things I have learned in college or university aren’t directly relevant for my position as a security researcher. I had to learn about many aspects of security on my own,” he says.

This is no doubt also the case with many other experts. There are a multitude of online learning resources these days, including countless massive open online courses (MOOCs) for people with various levels of skills and experience. Also, social networks, notably Twitter, and many other online services, including YouTube, offer great opportunities for people keen to exchange knowledge and experience, ultimately enabling them to learn from one another.

“It is true that the technology and security community is growing and many people are happy to share their knowledge, which allows newcomers to get support from established professionals,” says ESET Brazil researcher Daniel Cunha Barbosa. “While self-learning is a possible path and it is how many experts in the industry received their training, it is not the only option,” he adds.

Indeed, while security professionals need to continue to learn on their own and sharpen their skills almost daily, many will agree that there’s an undeniable value in academic training.

“If I had to do it again, I’d still choose to go through college and university. Both gave me the opportunity to meet people and participate in extra-curricular activities such as competitions and security conferences that I enjoyed so much. Some schools also offer internships, which also helps getting started in the field,” says Léveillé.

Formal cybersecurity programs

As online threats have increased dramatically, says Goretsky, so has the desire to standardize the pedagogical aspects of those who would learn to practice cybersecurity.

“I think that overall it is a positive thing that the wide range of cybersecurity education at all levels – not just university – is out there, but I also worry about its quality. We need theorists as much as we need operationalists, and we need those people to be well versed in the building blocks of very complex and complicated systems. A lot of that can be learned, but there’s still a considerable need for being autodidacts who can take what they are learning and build complex structures and ideas with that learning. Do the postgraduate courses and certifications allow people to expand on what they learned in university, or was what they were taught too limited or brittle a framework for them to provide a solid foundation for cybersecurity concepts? I don’t know,” he adds.

Cunha Barbosa adds that “the fact that there are specialization and postgraduate programs on top of degrees is itself a positive thing, since having a degree that gives the future expert broader educational foundations will allow them to learn about aspects of technology that go beyond security and will ultimately help them become better prepared for the challenges”.

In Canada, says Léveillé, colleges and universities are now offering an increasing number of information security programs. “There are now degrees with specialization in computer security. Before, the only option was to do software development or computer networking. Cybersecurity experts need both, with a different approach,” he said, before adding: “There is still a growing need in our industry that we must fill. With the effort from the educational programs, perhaps we will see a more stable situation in a few years.”

A lack of cybersecurity career awareness

Young people often have a hard time deciding what career path to follow, and many finish high school without having a clear idea about what they want to do next. Cybersecurity is often not on the radar of young people because many of them lack enough information about this – arguably less traditional – career path in the first place. Perhaps more important: their assumptions of what a career in cybersecurity actually involves may be very inaccurate.

“The trope or image of the disaffected youth being a hacker and attacking computers (or ‘conducting offensive cyber-operations’) and gaining fame and fortune or ‘full-spectrum information dominance’ is appealing to youth but what’s lacking is a realization that there is much, much more to cybersecurity as well,” says Goretsky.

That said, there is a sense that the general interest in pursuing a career in computer security has been trending higher in recent years, which may ultimately also help remove some of the common misconceptions.

“I see a lot more students interested in computer security than when I was a student myself. Before, it was something you’d have to be interested in on your own. Now there are enterprises and schools that encourage more students to enter the field. I think there’s a growing demand from the industry, perhaps due to the increase in attacks,” says Léveillé.

Turning briefly to the importance of incorporating security from the onset of software development, we asked Léveillé if he thinks that college and university curricula give students enough opportunities to learn security-by-design principles.

“I think that, nowadays, secure development is pretty well taught. However, the problem is that developers need the incentive to apply what they learn. Insecure code should be caught during code review and blocked from being included in the project. If developers see that their code is repeatedly rejected for security reasons, they will pay extra attention and will develop the right ‘reflexes’,” he said.

Conclusion

Given the growing range and constant evolution of threats, there’s clearly an urgent need to train and educate the next generation of IT security professionals and help plug the industry’s talent gap. Options and opportunities abound; at the end of the day, the future is bright for people looking to build a career in cybersecurity.

Microsoft issues patch for Internet Explorer zero‑day – 10 minute mail

The critical vulnerability could also be exploited via a malicious Microsoft Office document

Microsoft has shipped out a fix for a critical flaw in Internet Explorer (IE) that is being exploited in the wild. Tracked as CVE-2019-1429, the vulnerability is part of this month’s batch of regular security updates known as Patch Tuesday.

The zero-day is a remote code execution flaw that, according to Microsoft’s advisory, has to do with how the browser’s scripting engine handles objects in memory. The security hole affects all current IE versions and could be exploited by a threat actor to lure the victims to visit a malicious website via the browser.

“An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system,” said the technology giant. From there, the attackers could install programs, tamper with data; and create new accounts with full user rights.

Importantly, there’s another possible attack vector – and it doesn’t even require you to use IE for your typical web browsing needs. “An attacker could also embed an ActiveX control marked ‘safe for initialization’ in an application or Microsoft Office document that hosts the IE rendering engine,” said Microsoft.

Details are sparse about the nature of the attacks exploiting the vulnerability, which was discovered independently by researchers from Google, Resecurity and iDefense Labs. Resecurity did say, however, that the flaw has probably been exploited in conjunction with a previously discovered vulnerability listed as CVE-2019-0880. The company stopped short of attributing the attacks to a particular APT group, but said that it believes that the attacks have been carried out by a cyberespionage group to target a range of victims in various parts of the world.

There are no known mitigating factors or workarounds for users who cannot implement the fix promptly. To be sure, the zero-day is not the only reminder why you should waste no time in plugging security holes, especially those that require little in the way of user interaction.

Neatly summarized in this table by the SANS Technology Institute, this month’s bundle of security patches fixes 74 flaws across various products and services, including Microsoft Edge, Office, Exchange Server, and Windows Hyper-V. Fifteen of the vulnerabilities have been given Microsoft’s highest severity ranking of “critical”, with the rest listed as “important”.

Disposable mail integrations for your workflow – 10 minute mail

In the modern workplace, the work environment consists of many different teams, frameworks and tools to tackle complicated issues. It can be overwhelming to handle all the information transferred or continuously log into different tools to gather information. This is why Disposable mail offers 8 different software integrations, which sends web application vulnerability alerts from Disposable mail into your existing workflows or digital workplaces:

Integrating Disposable mail into your existing workflows makes it easier for your teams to communicate about web application security issues and whether it needs to be prioritized now or later. Depending on your account payment plan, the options for notification customization include alerts on the severity level of vulnerabilities (medium or high) and when scans are started and finished.

Teams are updated immediately when vulnerabilities are detected, and certain integrations allow for tickets to be issued right away. It allows for web application security to scale up with agile teams and working environments. Soon security will be second nature to everyone, that it’ll seem strange that security was ever seen as a separate function.

The Russian Embassy in Sweden responded to the Swedish Minister’s statement about “Russian trolls” – Disposable mail news

The Russian Embassy in Sweden reacted to an interview with Swedish Minister of Energy and Information Technology Anders Igeman to the TT Agency, in which he said that “Russian trolls” who are opponents of 5G technology attacked his Facebook.

Russia is open for cooperation with Sweden, especially with those of its representatives who are not looking for “Russian trolls”. The embassy of the Russian Federation in Sweden wrote about this on Tuesday on its Facebook page.

“We would like to assure the Minister of the fallacy of his opinion that the development of 5G technology in our country is associated with a negative impact on public health. On the contrary, we are open to cooperation with Swedish partners in this area, especially with those who do not suffer, as Anders Igeman, from paranoia in search of “Russian trolls”,” said the Embassy.

Anders Igeman said on Monday that an information attack was committed on one of his posts on Facebook organized by opponents of the development of the country’s fifth generation of mobile communication 5G. Almost 2 thousand comments were left to this message instead of several hundred. As the Minister himself noted, the content of most of the comments suggests that someone is interested in creating a negative information background around the topic of the development of a new generation of communication. Igeman believes that the “Russian trolls” did this.

“We are especially pleased that Anders Igeman connects the increased interest in his publication about 5G with our country. Judging by the scope of the reaction, almost all Russians who speak Swedish responded to the recent post of Minister!”, wrote the representatives of the diplomatic mission.

The Embassy promised to subscribe to the updates of the Swedish Minister and to closely monitor his activity in social networks.

At the same time, representatives of the Embassy expressed hope that Sweden will consider Russia not a threat, but a potential partner.

Disney+ accounts hacked – How to protect yourself – 10 minute mail

As users are losing access to their accounts by the dozens, we offer a few tips to help keep your streaming subscriptions safe

The long-awaited streaming service Disney+ was launched to the cheers of many. But it wasn’t without technical issues; in addition, within hours of the service going online many users were reporting that their accounts had been hijacked, writes ZDNet. The hacked accounts then started to appear on the dark web and were up for grabs for prices ranging from US$3-11, or even for free. To be sure, this account hijacking spree is not an isolated incident, and other popular streaming services have been battling such incidents for years.

Nevertheless, there are a few easy steps you can take to lower the chances of having to go through a similar ordeal in the future. The following advice should apply to a majority of widely used streaming services.

Fix your passwords

As basic as this recommendation may sound, a strong and unique password or passphrase can make a world of difference. Importantly, you should never recycle your password across various services or even use any variation of the same password or passphrase, as that can be easily guessed, too. Also, you may want to consider using a password manager to generate and store your passwords, which will require you to remember just one master password.

Another good precaution is to use a service such as Have I Been Pwned to check if any of your credentials may have been compromised in a past data breach. You can also sign up for notifications in case your login details show up in future breaches. Both Chrome and Firefox offer their own versions of password checkups.

Generally speaking, two-factor authentication (2FA) is an efficient way of bolstering your account security but, sadly, as of the time of writing many streaming services don’t offer this option.

Something smells phishy

Password-guessing isn’t the only technique that criminals leverage to hijack accounts. Bad actors often resort to social engineering and impersonate official channels of communication to hoodwink you into surrendering your personal data. Indeed, it may be safe to say that everyone from politicians to regular people has received a phishing email.

Although email service providers have ramped up their security measures and try to catch as many attempts as possible before they reach their targets, some wriggle through their nets from time to time. In these cases, you must rely on your wits – especially as many phishing attacks are no longer riddled with grammar mistakes and may overall look believable.

As a rule of thumb, you should never open any attachment or click on any link unless you are 100% sure that the message is authentic. If needed, contact the sender through other verified channels to make sure that they sent it. You can check out our earlier article that deals with phishing attacks in greater detail.

Prevent

Having healthy cybersecurity habits, taking a common-sense approach and using a reputable security solution will generally go a long way towards keeping you safe in the digital realm. In the words of Benjamin Franklin, “An ounce of prevention is worth a pound of cure” – and that applies a thousand-fold for cybersecurity.

Serverless vs Cloud vs On-prem – 10 minute mail

Server architecture can differ in a lot of ways, but the three main categories would be on-prem, cloud and serverless. Some believe that cloud and serverless can be used interchangeably, which is not the case. To help clear up some confusion, this blog post will explain each of them and how it affects security work.

A physical server that you own

On-prem stands for on-premises which means that the server are located on the premises of the company. This is a physical server hosted at the company, a data center the company has their servers at, and so on.

Similarly, when talking about buying a on-prem solution it is software that could be shipped as a server that you place in your own data center or something that you install on an existing server.

In this kind of setup you have full responsibility of all security aspects: the application layer, keeping servers up to date and replacing old hardware. This might also require specialists or vendors to come on-site to service things when needed. If service of security updates are not kept up-to-date, hackers are bound to find a way in a exploit the opportunity.

On the other hand, you have full control over your data and depending on traffic flow it might be cheaper.

Where does Disposable mail fit in?

Disposable mail can help you scan web applications that are hosted like this today. However, you cannot buy our service as a on-prem solution in the sense of a server that you install in your data center or as software to install on your own. Our service is only available on our own infrastructure which we then scan your servers from. This ensures the service is constantly updated, both with new vulnerability tests but also from a security view.

A virtual server on a server which someone else owns

Today it’s easy to run your own operations without needing your own physical servers. Someone else, such as Amazon or Google, has their own massive data center with physical servers that in turn emulate smaller ones. The Cloud is not really mysteriously in the air, rather it’s when you rent of these virtual servers.

With this option you are free of the physical aspects of maintaining your own server, but there are similar responsibilities. You still need to keep all software including operating system up to date, configure firewalls, and related tasks. However, you do not have to think about replacing old hardware, making sure there is backup electricity, and so on.

This is similar to what we do at Disposable mail. In fact, every time you start a scan we start a new virtual machine at Amazon. This is good for scalability and for security as it is one way of ensuring information does not leak between customers. We would not be able to buy a new physical server each time, but virtually we can do this.

Disposable mail for companies in the cloud

The security of the server and application is your responsibility even if the server is not physically close to you. The cloud provider is responsible for the actual infrastructure or hardware, but everything on the software layer is on you. Security of web applications are always on you, regardless on how you host them.

A function on a server that someone else owns

It is here where it may start to get confusing. Going serverless is often confused with the virtual machine solution described above, but these are actually two separate things. In that kind of a cloud solution you do have your own server, albeit a virtual one. In a serverless solution you do not. Serverless can also be called Function as a Service, or FaaS. Two popular alternatives are AWS Lambda and Google Cloud Functions.

Serverless is a sub-category of cloud solutions, but in the previous part we decided to focus on virtual machines as that is the most common application.

In the virtual machine you are writing code that constantly runs. You have a web server which in turn calls on other code whenever someone access a specific page. In a serverless solution you instead write code that is triggered by events. Instead of maintaining your own server, you can upload the code to eg. Amazon and let them trigger each function based on events such as someone uploading a file to a Amazon S3-bucket.

An example use-case would be to create a simple HTTP API-interface that creates an event when it receives a request. A serverless function gets triggered by this event, takes the data from the API-call, modify it and then saves it in a Google Firebase database. This itself creates another event for another serverless function to react to.

A core thing about serverless is basically tying together these kind of services. This means that you can create code reacting to those events, and you only pay for when they actually are running. The code runs on servers owned by someone else (again, most often Google/Amazon/Microsoft) and as such you do not need to worry about maintaining the server.

How does Disposable mail help serverless?

If you use third-party services the configuration of those is very important. We have done a lot of research related to such usage. Examples on this would be the research we on S3-buckets or when we dug into upload policies and signed URLs. Such knowledge is implemented into our core service and something that we look for during a scan.

And even if there is no server to maintain, you are still responsible that the code is secure. Many traditional web application vulnerabilities still affect serverless applications.
