10 Cybersecurity Myths

Myth1.png

A new infographic by Varonis, titled “10 Cyber Security Myths Putting Your Business at Risk” identifies what is the myth and what is the reality. If you are like most small business owners, you probably aren’t a digital security expert. So, having a look at this infographic may be the best way to identify weaknesses in your security protocol.

With small businesses increasingly becoming targets of cyber-attacks, it is extremely important for owners to stay abreast of the latest developments in digital security.

On the official Varonis blog, Senior Director of Inbound Marketing Rob Sobers writes, “The proliferation of high-profile hacks in the news cycle often tricks small- and medium-sized businesses into thinking that they won’t be targets of attack.”

But this may not be the case, Sobers warns. Staying in the know makes it much harder for you to fall victim to the relentless attacks by cybercriminals.

Sobers ads, “If you or your employees believe any of the myths below, you could be opening up your business to unknown risk.”

strong-passwords-myth

The number one myth listed on the new infographic? ‘A strong password is enough to keep your business safe’. Although a strong password is important — and certainly better than ‘Admin1234′ — you need to do more.

Having a two-factor authentication and data monitoring adds another level of protection. And adding this layer of protection is in many cases enough to drive the average hacker to look for easier targets.

small-businesses-hacked-myth

Another myth listed on the infographic? “Small and medium-size businesses aren’t targeted by hackers. This is obviously false because hackers are opportunists who will target anyone as long as they can benefit from it. And small businesses are not excluded from this.

The 2018 Verizon Data Breach Investigations Report has revealed 58 percent of data breach victims are small businesses, so the idea the size of your business might exclude you is definitely a myth.

Cybercriminals hack computer systems for a variety of reasons. Once they breach your security, they could use it to launch a DDoS attack, use your IP address for other nefarious purposes and more.

industries-vulnerable-hacking-myth

Much like some businesses believe they won’t be attacked because of their size, other businesses wrongly assume that they won’t be attacked because of the industry they’re in. This myth also goes hand-in-hand with the belief that some companies don’t have anything “worth” stealing. The reality is that any sensitive data, from credit card numbers to addresses and personal information, can make a business a target.

What’s more, even if the data being targeted doesn’t have resale value on the dark web, it may be imperative for the business to function. Ransomware, for example, can render data unusable unless you pay for a decryption key. This can make attacks very profitable for cybercriminals, even if the data is deemed “low value.”

anti-virus-myth

Anti-virus software is certainly an important part of keeping your organization safe — but it won’t protect you from everything. The software is just the beginning of a comprehensive cybersecurity plan. To truly protect your organization, you need a total solution that encompasses everything from employee training to insider threat detection and disaster protection.

insider-vs-outsider-threats

While outsider threats are certainly a concern and should be monitored extensively, insider threats are just as dangerous and should be watched just as closely. In fact, research suggests that insider threats can account for up to 75 percent of data breaches.

These threats can come from anyone on the inside, from disgruntled employees looking for professional revenge to content employees without proper cybersecurity training, so it’s important to have a system in place to deter and monitor insider threats.

IT-cybersecurity-responsibility

While IT has a big responsibility when it comes to implementing and reviewing policies to keep companies cyber safe, true cybersecurity preparedness falls on the shoulders of every employee, not just those within the information technology department.

For example, according to Verizon, 49 percent of malware is installed over email. If your employees aren’t trained on cybersecurity best practices, like how to spot phishing scams and avoid unsafe links, they could be opening up your company to potential threats.

public-wifi-password-myth

If your business has employees who travel often, work remotely or use shared workspaces, they may incorrectly assume that a password keeps a Wi-Fi network safe. In reality, Wi-Fi passwords primarily limit the number of users per network; other users using the same password can potentially view the sensitive data that’s being transmitted. These employees should invest in VPNs to keep their data more secure.

computer-infected-myth

A decade or so ago it may have been true that you could tell immediately if your computer was infected with a virus — tell-tale signs included pop-up ads, slow-to-load browsers and, in extreme cases, full-on system crashes.

However, today’s modern malware is much more stealthy and hard to detect. Depending on the strain your computer or network is infected with, it’s quite possible that your compromised machine will continue running smoothly, allowing the virus to do damage for some time before detection.

BYOD-security-myth

Employees often assume that their personal devices are immune to the security protocols the company’s computers are subjected to. As such, Bring Your Own Device (BYOD) policies have opened up companies to the cyber risk they may not be aware of. Employees who use their personal devices for work-related activities need to follow the same protocols put in place on all of the network’s computers.

These rules aren’t limited to cell phones and laptops. BYOD policies should cover all devices that access the internet, including wearables and any IoT devices.

cybersecurity-preparedness-myth

Cybersecurity is an ongoing battle, not a task to be checked off and forgotten about. New malware and attack methods consistently put your system and data at risk. To truly keep yourself cyber safe, you have to continuously monitor your systems, conduct internal audits, and review, test, and evaluate contingency plans.

Keeping a business cyber safe is a continuous effort and one that requires every employee’s participation. If anyone at your company has fallen victim to one of the myths above, it may be time to rethink your cybersecurity training and audit your company to assess your risk.

How protected are you against cyber-attacks?

People often say you can’t truly understand something until it happens to you, which is true in many situations in life. We can’t imagine data security issues impact our lives.

All infrastructure is vulnerable to attack.

There is no magic platform that is completely impenetrable now and in the future. Despite what you may see in advertisements, no vendor, no firewall, no router, no hardware, no operating system, and no software product can block all possible attacks.

This is why information security is a process that begins when a system is being planned, and monitors, evaluates, and corrects security issues throughout the lifetime of the system, and continues until the system is decommissioned and its components securely disposed of.

What are the cybersecurity attacks?

Cybersecurity refers mainly to protecting internet-connected systems, including hardware, software, and data, from cyber attacks. Cyber attacks can result in the following issues:

  • Data theft
  • Ransomware installation
  • Data corruption
  • Spyware

I thought you could use a starting point, a guide you can use to do a personal security risk assessment, so you can then take the necessary actions to improve your protection from cyber-attacks.

In order for your data to be secure, it has to check 3 important factors. We want our information to:

  • be read by only the right people (Confidentiality)
  • only be changed by authorized people or processes (Integrity)
  • be available to read and use whenever we want (Availability).

Picture2

When going through the questions below and answering them honestly (no grades will be given), keep in mind these three principles. This security risk assessment is not a test, but rather a set of questions designed to help you evaluate where you stand in terms of personal information security and what you could improve.

  1. What type of information do you have stored on your computer (pictures, work documents, applications, passwords, etc.)?

It will be really useful to make a list of the different types of information you have stored:

  • Locally, on your computer
  • Online, in different apps (cloud-based or not) and on various websites.

Do you have personal emails, work documents, confidential corporate data, photos and videos of your family or personal information, such as banking credentials or passwords?

  1. Which online services do you use more often?

Think of the online services you use on a daily or weekly basis. You could list:

  • Online shopping
  • Social networking
  • Online banking
  • News websites
  • Download portals
  • Chat applications, etc.
  1. Define how valuable each asset to you.

You can use three degrees of importance: “low”, “medium” and “high”. Define this value based on the potential cost (financial, reputational or emotional) of an unauthorized person gaining access to that piece of information or service.

For example:

  • Online banking password – high value
  • Playlist stored on your music streaming service – low value.
  1. How do you keep your sensitive information safe?

Consider the following options (and others that apply to your situation):

I use strong passwords (longer than 8 characters and including symbols and numbers)

I use passwords for both my online accounts and for logging into my laptop/tablet/phone

I use two-step authentication whenever it’s available

I have set strong security questions in the event of a security breach

I have my email accounts connected so I can regain access to my information in the case of a cyber attack

I set up my phone number to receive alerts from important services (such as online banking or email) in the case my accounts should be compromised.

  1. What kind of security are you using?

Do you have an antivirus solution installed? Do you update it regularly? And, most of all, do you know that antivirus is not enough?

In order to understand why antivirus is not enough, you’ll need to learn about the difference between an antivirus and an anti-spyware product. To put it briefly:

  • When you’re already infected, antivirus programs detect if a virus is on your PC and they remove it.
  • But what you need is not to get infected in the first place.
  • So that’s why you need a tool that can work proactively to detect and block malware.
  • Another layer of protection you could use is a firewall and even an encryption application that can ensure that your data won’t be accessed in case your gadgets are stolen.

Before choosing any cybersecurity product, make sure to do some research and learn about what the product offers, check AV testing websites (AV TestAV ComparativesVirus BulletinPC Mag) and other reviews that compare options, so that you can make the best choice for you.

  1. What security software are you using against financial and data-stealing malware?

Cyber-attacks directed at collecting financial information and leaking confidential data are increasing in numbers and severity. This is why, in order to conduct online transactions with peace of mind, browse the web securely and keep your private information secure, you’ll need a dedicated product.

In order to get protection against financial malware, the solution you need should:

  • include a real-time Internet traffic scanner that scans all incoming network data for malware and blocks any threats it comes across
  • be able to provide malware detection and removal of malicious software that has already been installed onto a computer
  • have a website security scanner feature that checks the website you want to visit, detects malware and blocks it.
  1. Are you using a backup solution for your operating system or for your vital information?

Keeping your data backed up is crucial for your cyber security plan. Evaluate your options: would you rather use an external drive or a cloud based solution? Weigh in the pros and cons for each, but be sure to keep the essential information you deem valuable safe.

Backup your data regularly in order not to lose the important progress you’ve made. There’s even a World Backup Day celebration happening on March 31 to help you remember!

  1. How do you protect your shared documents (e.g. Google Docs) or gadgets (computer, tablet, etc.)?

Do any other people use your gadgets? Have you set up guest accounts for them or do they have access to the administrator account? Do you have kids that use your gadgets (and have you taught them about information security)?

I know these seem like a lot of questions, but the human factor is the most common cause for cyber-attacks because hackers know how to manipulate and trick the vulnerable categories into revealing information or installing malicious software.

Also, keeping a back-up of shared documents and files could save you the trouble of having to do the work all over again if someone should delete or modify those files. When possible, be sure to offer view-only permission and regularly check who has access to confidential information (after a colleague’s departure from the company, after a break-up with a spouse or boyfriend/girlfriend, etc.).

Maintain a vigilant attitude and, to the extent that you can, try to share valuable these what you’ve learnt from this security risk assessment with those around you, especially with the people you shared gadgets or accounts and documents stored in the cloud with.

  1. How do you manage your passwords?

You’ve probably accumulated plenty of passwords by now, which is what makes it so difficult to manage them. You may be tempted to use the same password more than once and make it easy to remember, but, by all means, NEVER do that!

 The safest way to manage your passwords is to use a password manager application, like LastPass. You should use a generator to create long, complicated passwords and store them in LastPass, and NEVER, EVER store them in your browser.

Picture2

This is especially recommended if you’re using your personal device at work. Don’t forget to password-protect your devices as well, and remember to lock/log off each time you leave them unattended.

It may take a bit to set things up at first, but, when you’re done, you’ll have more peace of mind and have a simpler way to manage your passwords.

  1. Do you regularly update the software you use?

Consider some of these choices:

Do you perform operating system updates when you’re prompted to do so?

Do you have automatic software update set up for both your OS and your applications?

Do you regularly update Oracle Java, Adobe Reader or Adobe Flash, which are known to cause 85% of security exploits that hackers use?

Do you keep your browsers updated to the latest versions?

Picture1

One of the most common and dangerous types of cyber attacks that hackers engineer are called “social engineering” strategies. These attacks entail the psychological manipulation of the victim to trick the person into divulging confidential information. The purpose can be information gathering, fraud, or system access.

So, ask yourself: do you reply to e-mails received from unknown people? Do you trust strangers and talk openly about your digital assets? Think about how you behave online and then adjust your habits so that you can become your own layer of protection.

How to Stay Protected Against Ransomware

How to Stay Protected Against Ransomware
                                           How to Stay Protected Against Ransomware

 

To prevent a ransomware attack, experts say IT and information security leaders should do the following:

  1. You can’t protect what you don’t know exists:

Developing an inventory of your assets is crucial. Keep clear inventories of all of your digital assets and their locations, so cyber criminals do not attack a system you are unaware of.

Be in a position to answer the questions instantly like:

  • How many PCs from a particular manufacturer do you have in your environment?
  • Which desktops/laptops are running an operating system that its vendor recently stopped supporting?
  • Which IT assets have a particular piece of software installed?

2. Keep all software up to date, including operating systems and applications:

Updates are important. They are available for both our operating system and individual software programs. Performing these updates will deliver a multitude of revisions to your computer, such as adding new features, removing outdated features, updating drivers, delivering bug fixes, and most importantly, fixing security holes that have been discovered.

3. Use A Supported Operating System:

Just because your old computer is still running doesn’t mean that you’re going to continue to receive updates. Both Apple and Microsoft stop providing updates for older operating systems. For example, Microsoft no longer provides updates for Windows XP, and Apple does not provide updates for early versions of OS X.

If the creator is no longer providing updates for a particular operating system, then that operating system becomes more dangerous every day you continue to use it. If a new vulnerability emerges, an update to remove the vulnerability may never be released. Virus writers know this and use it to their advantage, often preying on computers that are not just behind on a few updates, but computers still running an unsupported operating system.

Therefore, it is important that you are running a maintained operating system, one that is still receiving updates.

4. Use an Antivirus Program:

An evergreen solution to prevent against most threats is to use a good antivirus software from a reputable vendor and always keep it up-to-date.

5. Regular Backup your Files:

Back up all information every day, including information on employee devices, so you can restore encrypted data if attacked. Better safe than sorry.

3-2-1 Backup strategy is good.

3-2-1 strategy means having at least

  • 3 copies of your data
  • 2 local copies on different storage types
  • 1 backup off-site.

6. Segment the company network:

Don’t place all data on one file share accessed by everyone in the company. Separate functional areas with a firewall, e.g., the client and server networks, so systems and services can only be accessed if really necessary.

"Good network segmentation is not going to make it impossible to 
compromise your network, but it does make it more difficult."

        ~ Mat Gangwer, security operations leader, Rook Security Inc.

7. Train and re-train employees in your business:

Your users can be your weakest link if you don’t train them how to avoid booby-trapped documents and malicious emails.  As ransomware is commonly introduced through email attachments and links, arming employees with the knowledge they need to practice secure email and browsing habits can prevent many ransomware attacks from succeeding.

Train employees on how to recognize phishing attacks as well as best practices such as not opening attachments or links in emails from unknown senders, checking link URLs, and never clicking pop-up windows.

Training should be ongoing rather than a single session to ensure that employees keep up with new threats and maintain secure habits.

8. Develop a communication strategy to inform employees if a virus reaches the company network:

The speedy dissemination of information is vital in stopping an attack or the continuance of an attack. It is vital that all users on the network be made aware of an attack or attempted attack to ensure the vigilance of other users on your network. It is likely that other users have also received similar phishing emails and your quick response may prevent further damage.

9. Instruct information security teams to perform penetration testing to find any vulnerabilities:

The Penetration tests must be carried out periodically either by Third party organization specialized in Security Testing or by the specialized internal resource. Periodic assessment of its information assets, network equipment, and applications should be conducted and fixed all gaps found during the assessment.

10. Keep Your Knowledge Up-to-Date:

There’s not a single day that goes without any report on cyber-attacks and vulnerabilities in popular software and services, such as Android, iOS, Windows, Linux, and Mac Computers as well.

So, it’s high time for users of any domain to follow day-to-day happening of the cyber world, which would not only help them to keep their knowledge up-to-date but also prevent against even sophisticated cyber-attacks.

Mitigating an attack:

If your company is hacked with ransomware, you can explore the free ransomware response kit for a suite of tools that can help. Experts also recommend the following to moderate an attack:

  • Remove the infected machines from the network, so the ransomware does not use the machine to spread throughout your network.
  • Launched less than a year ago, the No More Ransom (NMR) project has started as a joint initiative by Europol, the Dutch National Police, Intel Security, and Kaspersky Lab, No More Ransom is an anti-ransomware cross-industry initiative to help ransomware victims recover their data without having to pay ransom to cyber criminals.

The online website not just educates computer users to protect themselves from                  ransomware, but also provides a collection of free decryption tools.

The platform is now available in 14 languages and hosts 40 free decryption tools,           supplied by a range of member organizations, which can be used by users to decrypt their files which have been locked up by given strains of ransomware.

  • Boston-based cyber security firm Cybereason has released RansomFree — a real-time ransomware detection and response software that can spot most strains of Ransomware before it starts encrypting files and alert the user to take action.

    RansomFree is a free standalone product and is compatible with PCs running Windows 7, 8 and 10, as well as Windows Server 2010 R2 and 2008 R2.
