Prey or Empowered? Small Businesses and IT Security

Now more than ever, small businesses need to be vigilant with their information technology security. Small businesses may not be the big fish in the sea, but there are plenty of them out there to catch. Small businesses tend to make the best targets because they often fail to perform security audits, they may not be willing to invest in the resources needed to protect themselves, and they frequently don’t even carry the right insurance coverages. To hackers, small businesses are easy prey.

“Don’t think you are too small to be affected,” says Erik Knight, the founder and CEO of SimpleWAN. “Every place you have an employee or office is a potential entry point. Take it seriously; if you have something worth taking, a hacker will try to take it.”

There are a few things every business can do to improve the security and privacy of their data. It isn’t an option any longer; these are essential elements in an overall security strategy that can make the difference between staying in business and not.

Use strong passwords, not easy-to-guess words, phrases or sequences (1234 is not a strong password). Passwords should be unique, more than 8 characters in length, and have a mix of numbers, letters, and special characters.

Keep software updated. Whether it is the operating system on your computer or the software you use to write letters, having up-to-date software matters. Developers don’t just upgrade software to fix bugs or introduce new features; software often gets updated because of security issues or vulnerabilities.

Keep networks and connected devices secure to make sure that the computers and connections aren’t introducing weaknesses into your system. Not only are password controls and software updates needed, but firewall security and good anti-virus/anti-malware solutions are also a must. Keeping an eye on the server matters, but the connecting points and end points are where many vulnerabilities exist.

Set up two-factor or multi-factor authentication to further secure logins. 2FA and MFA is like having ID besides just your driver’s license to prove you are who you say you are. Your password, like your DL, is just one factor; you need one more thing to prove your identity for 2FA, like a code from your phone or maybe your fingerprint. The point is that there should be more than just a username and password to access important data.

Restrict use of personal email or social media on work devices. This gets a little trickier with smaller businesses, as many don’t or can’t support providing users with all company-owned devices. There are tradeoffs to allowing users to bring their own devices (byod) versus using company-owned devices. When mobile devices are part of the mix along with desktop and portable computers, it becomes even more complicated and the risk potential increases.

Use encryption for data in transit and data at rest. Encryption is like scrambling the data and then unscrambling it when you access it. In transit, data may be encrypted by a VPN so that it is protected over the wire (in motion) as it is sent and received on the network. RDP is also encrypted, but this remote access method’s main purpose is to keep the data from leaving the server in the first place. At rest, like when it is sitting on a hard drive or other storage location, data can also be encrypted. To open the file or file system, you need a key to decrypt it.

Keep all data backed up and create a way to rapidly recover your server and systems in the event of failure or compromise. Backups are great right up until you find they are as damaged or unrecoverable as your main system, so make sure to have a policy of testing your backups periodically. There are many ways to back up and protect your data, including external drives and cloud storage. If data gets lost or corrupted, you want to be able to restore it from a backup. Regularly audit your backup and data security practices to help identify weaknesses that make the business vulnerable.

Educating employees on the importance of cyber security is among the most important steps a business can take to protect itself. Keeping passwords secure and secret, knowing how to spot a phishing email and what to do and not do with it, not clicking on suspicious links in emails, not sharing personal or confidential information online, and what to do in the event of a breach are all things that should be regularly discussed with workers and supported by written policies.

Managed Azure cloud servers from Noobeh help you keep your business information more secure. Our services demand high levels of security and privacy, and we help our customers keep their data and systems safer and more secure by handling some of the requirements for them.

  1. Strong password policies and MFA is our standard setup, and software updates and patching are part of the service.
  2. Working on the cloud server keeps data on the server and not traversing the network or downloading to individual PCs, so information stays secure and separate from whatever a user runs on their local devices.
  3. Data on the Azure virtual machines is encrypted at rest, and additional encryption is available to add more layers of protection. Data in motion is encrypted, but very little data actually traverses the wire.
  4. Servers and data are backed up regularly with snapshots and file level backups, allowing for simple file restores as well as comprehensive system recovery.

For small businesses, Noobeh has the solution for creating a more secure and better protected IT environment where applications and data can be available to those who need them without compromising the investments already made in training and process development. Moving software and data to a private cloud server allows companies to continue using the software they rely on, just in a better way. Instead of being easy prey to hackers, our customers benefit from higher levels of IT administration, management and protection that empowers them to work the way they need to – any time, anywhere.

ZERO TRUST – Every Email is Suspect

Electronic mail has become a standard for communications around the globe. Email can contain not just text, but can deliver documents, photos and videos and other media. Email allows people to contact others at any time and respond on their own schedule. Where previous methods of communicating with someone far away were expensive and time-consuming, email allows people to stay in touch no matter where they are as long as they can connect to the internet.

Yet email is not a fully secure communication medium, and a lot of people are just now figuring out just how vulnerable they may be. What was once considered a trusted means of communication has now become something to be suspicious of. For most users today, it is best to approach emails with a high degree of suspicion (zero trust), especially if they ask for personal information or contain links or attachments.

With email, someone could intercept the messages or even store messages without your knowledge or control. The smallest human error can have ripple effects that turn into waves of trouble because messages cannot usually be taken back. And then there are the threat actors, of which there are too many and they are far too clever.

Phishing has become a highly popular method of cyber-attack, probably because it works so well. It involves tricking people into giving away sensitive information like credit card numbers, social security numbers, and passwords. Phishing is fueling (phueling?) opportunities for malware infections and identity theft which can lead to financial loss, reputation damage and more. Any information an attacker can gain helps them get even more information and go deeper into the organization.

Protecting against phishing attacks requires vigilance and following best practices such as using strong and complex passwords, and two-factor or multi-factor authentication (MFA). Also, it is crucial that users avoid clicking on links in emails, and everyone should verify the email authenticity before responding, especially if sensitive information is involved.

To check the identity of the sender, mouse over (put your cursor over) the email address and it may show you the actual sender address. While the email may say the message came from somebody you know, you may find that the actual sender address is an obscure email address you don’t recognize.

Mouse over links in the email but don’t click on them. When you hover your cursor over the link, it may show you the actual url the link goes to. Like with email addresses, links can be named something other than the actual url. If it is a url or website name you recognize and trust, then type the url into your browser instead of clicking on the link, just in case.

Use multiple channels for communication. This means you should not just communicate with co-workers and others using email. It is always a good idea to have some other form of trusted means of communicating with someone, such as via telephone or a messaging application. When you receive an email requesting sensitive information or an email with file attachments, you should communicate with the sender on one of your other communication channels to verify the authenticity of the email or attachment.

Never ask the sender to verify their identity over the same channel as the original communication. If it is a hacker, you’ve just verified to them that they reached their target.

4 Rules of Thumb for Better IT Security

Your business is a target. The simple fact of being in business makes it so. There are a lot of bad actors out there who will go to great lengths to get your personal and financial information, and they have many different and innovative approaches to get it. There are some small steps any business can take to make a big impact in protecting business data.

Here we present our 4 Rules of Thumb for better IT security; a starting place if you’re looking for somewhere to begin.

We can’t stress enough that every business should make it a priority to implement some basic information/technology security standards and regular employee training. Having more discussion on the subject helps everyone in the company learn and shows that management is paying attention. Remember that business data isn’t just word documents and spreadsheets. It’s banking and financial and other information, employee information like social security numbers and direct deposit info, customer, vendor information and more. For even a small business, the possibility data exposure or loss isn’t trivial.

NOOBEH cloud services works to keep your QuickBooks on Azure cloud deployment more secure in a variety of ways, but we always start with a few essential policies. These rules and policies can mean the difference between a small IT annoyance or catastrophic failure and data encryption, loss, or exfiltration. If you haven’t implemented these four essential policies in your business IT environment, today is the day to start.

  1. Always use strong passwords, at least 10 to 12 characters, and make them complex. Require passwords to be updated periodically. Don’t reuse passwords and avoid common words or phrases.
  2. Don’t let users operate with permissions greater than required. In applications, consider restricting functionality based on the role or job requirements. On servers and PCs (Windows, Mac, whatever), make sure users are operating as “standard” users rather than system administrators. When you reduce the permissions granted to users you prevent their accounts from performing possibly harmful actions in the system, like installing malware or damaging programs, modifying settings, or even creating backdoor user accounts.
  3. Control user account information and manage it closely. Simply knowing what user accounts exist can give hackers and phishers enough information to begin targeting logins and applying methods to crack them. Part of this includes making sure to remove or disable accounts for user accounts that are no longer needed. Every unused account that remains enabled is just another point of vulnerability. Protect system and administrative accounts and directories (like Microsoft Active Directory). Make certain that you only grant access to sensitive system and account information when absolutely necessary, and only to a completely trusted source. Also make sure to have at least one “break the glass” (back door) admin account you can use if the regular administrative account(s) become compromised.
  4. Limit the installed software to what is needed for the business and keep it current. Make sure operating systems and applications are up to date, and keep browsers and plugins updated to make sure they don’t become the weak link.

Cyber criminals are delivering waves of cyber-attacks that are both highly coordinated and far more advanced than ever before seen. Endpoint attacks have become complicated multi-stage operations, ransomware hits small business and enterprises alike, and stealth crypto mining got criminals into unsuspecting corporate networks. The year has been awash with massive data leaks, expensive ransomware payouts and the realization of a completely new and extremely complicated threat landscape. The bad guys have upped their threat game in a big way.

Diligence is required to help protect valuable business information assets. Following these four rules of thumb will help the business avoid becoming easy prey and can provide a foundation for greater system security and a more streamlined approach to identity management, applications and access.

Cybersecurity Terms Every Business Owner Should Know, and Zombies are Bad

The world of cybersecurity constantly changes, making ongoing education the key to understanding the threats businesses face and how to possibly deal with them.

Cybersecurity is often defined as a set of techniques for protecting an organization’s digital infrastructure – the networks, systems, and applications – from being compromised by attackers and other threat actors. Cybersecurity is comprised of the efforts to design, implement, and maintain security for any organization network which is connected to the Internet.

Cybersecurity is made up of the technology, people, and processes which create strategies to protect sensitive data, ensure business continuity, and safeguard against financial loss.

To understand what cybersecurity entails, it is important to have a basic understanding of the relevant terminology.

Starting with a few that are frequently misused, here are some cybersecurity terms to add to your business vocabulary.

Data are the bits and bytes. When multiple bits and bytes are combined, they make up information. Knowledge is required to turn information into action.

A threat is the possibility that something bad that might happen, while a risk includes the probability of the bad thing happening and the possible result.

Risk Management is the process of responding to the possibility that something bad might happen. Traditionally, there are four options for managing risk in the business: accept it, transfer it to someone else, avoid it altogether, or mitigate it (reduce the severity).  To manage cybersecurity risk, many businesses establish requirements or controls to identify activities, processes, practices, or capabilities an organization may have. Controls may or may not be mandatory, but requirements generally are.

Information Security, or Information Assurance, is the protection of facts, news, knowledge, or data in any form. Information Assurance is an important aspect of preserving business resources and is often combined with cybersecurity, although it isn’t squarely in that area. Where cyber addresses digital, information security must also address non-digital such as paper, human knowledge or memorized, stone tablets, pictures, and signals or whatever.

Authentication is the process of proving an individual is who they say they are (claiming an identity and then proving it), whereas authorization is the use of access controls to determines and enforces what authenticated users are permitted to do within a computer system. Access Controls are the means and mechanisms of managing access to and use of resources by users.

Audits, in cybersecurity, are usually performed after a security incident. In general, an audit is an official inspection of some type. An assessment is often more like a health check for gauging capability or status. Audits may be performed internally or by outside entities. Compliance is meeting a requirement, whether internal or external. Sometimes these are regulatory requirements where a certification or attestation of some type is shown. Both audits and assessments may be required to be compliant with certain standards or designations.

A cyberattack is any attempt to violate the security perimeter of a logical environment. This could be a single computer system, a local or wide-area network, a cloud server, etc. – whatever is within your “perimeter” and is interconnected with your systems, regardless of location in the physical world. Cyberespionage, on the other hand, is the unlawful and unethical act of violating the privacy and security of an organization for the purposes of leaking data or disclosing internal, confidential, or private information.

And then there’s malware (malicious software), which includes any code that is written for the specific purpose of causing harm, disclosing information or in some other way violating the security or stability of a system. The malware category includes lots of different types of terrible and potentially damaging programs including virus, worm, Trojan horse, logic bomb, backdoor, Remote Access Trojan (RAT), rootkit, ransomware, and spyware/adware and more.

To better-secure your systems, multi-factor or two-factor authentication is suggested. Multi-(multiple) factor and two-factor authentication are a means of verifying a “claimed” identity using two or more types of proof (authentication factors). The password is typically the initial proof provided, and the other factor/method might be SMS to your phone or possibly an authenticator app.

For example: You claim that the email address is your identity, and you verify that by entering your password. That is one “factor” that proves your identity. But if your password gets hacked or revealed, it would be good to have another layer of protection on that login. Two is better than one in this case; MFA (multi-factor) and 2FA (two-factor) authentication is considered stronger than any single factor authentication and requires another method (factor) of identification to prove your identity.

Finally, there are zombies. Yes, Zombies. This is a term that relates to the concept of a malicious network of “bots” (a botnet). Botnets are made up of poor, innocent computers that are compromised by malicious code so that they can run remote control or other agents. The agents give the attackers the ability to use the system’s resources to do nefarious things, like perform illicit or criminal actions. The zombie can be the system that hosts the malware agent of the botnet, or it could be the malware agent itself. Either way, zombies are bad.

Security is an essential consideration for every business, and the Internet and the interconnected design of today’s technology has made things so much more complicated. The most important thing is to be aware of the threat and how that landscape is changing, and to educate team members so that everyone in the company participates in keeping the system, and the business, protected.

The Question You Never Want to Have to Ask

Why MFA Shouldn’t Be Optional

“Do you offer any help for decrypting files due to ransomware?”

This is a question we are asked with more frequency than ever before. And, sadly, it is often followed up with the information that their files were on “an internal server that was missed in the backup protocol by IT”.

Email phishing and brute force attacks are the most common methods cyber criminals use to get into your business network where they can set up to initiate ransomware attacks. The ransomware (malware) encrypts your data, which becomes unrecoverable without the decryption key. Usually, the only way to recover from a malware/ransomware attack is to rebuild systems and restore data from backups. If you have backups.

A “brute force” attack is typically used to get personal information such as passwords or passphrases, usernames, and Personal Identification Numbers (PINS). Scripts or specialized apps are used to carry out a string of continuous attempts to get the information desired. Cybersecurity researchers at Coveware analyzed ransomware attacks during the second quarter of 2021 and found that phishing and brute force attacks on unsecured desktops (remote and local) are among the most popular entry points for starting ransomware attacks. This is at least partly because it is relatively cheap and can be highly effective.

Phishing attacks are when cyber criminals send emails containing a malicious file attachment or hyperlink directing to a compromised website that delivers ransomware. Attacks against desktop logins include methods where cyber criminals use brute force to leverage weak or default usernames and passwords – or even get access because they got legitimate login credentials via a phishing email.

Software vulnerabilities and web-based application services are also among the popular vectors for delivering ransomware or exposing corporate networks to cyber criminals. While this type of attack is somewhat less frequent than the others, they are often leveraged by some of the most sophisticated and disruptive ransomware groups and nation/state bad actors.

  • Sodinokibi – also known as REvil – is responsible for some of the most high-profile ransomware attacks this year, including the massive ransomware attack on customers of Kaseya.
  • Contij – one of the most high-profile attacks by the group was the attack against the Irish healthcare system. Healthcare services across Ireland remained disrupted for months.
  • Avaddon – ransomware distributed via phishing emails.
  • Mespinoza and Hello Kitty are new forms of ransomware recently identified.

All of these have a common purpose in that they take advantage of weaknesses in security and exploit phishing tactics to lay the foundation for an attack on your network and possibly others.

Keeping systems updated, applying security patches and application software updates is an important aspect to keeping things secure. Known vulnerabilities can be exploited to gain access to the network, so keeping up with updates as the vendor supplies them has become more important than ever.

To help protect networks from being compromised, businesses should also apply multi-factor authentication (MFA) to desktop and applications.

MFA is an important tool to help stop intruders from breaching accounts and gaining access to the corporate network, and it can be the difference between keeping your data safe and working or discovering your files are digitally encrypted and completely unusable. Data encryption changes the data into code, and only the decryption key can read the code and return the data to a useable form. If you don’t have the key, the data typically cannot be decrypted.

Cyberattacks continue to evolve in their sophistication and frequency, and consequences of such attacks are growing. Private companies and public agencies alike must adapt their security techniques and embrace new security technologies while providing more end-user education and training.

Mendelson Consulting and NOOBEH Cloud Services take security very seriously and we have the experience and expertise to assist businesses with transforming their operations to be more efficient and effective. Our cloud team works exclusively with private tenant accounts on Microsoft Azure, and offers MFA security and other solutions to protect local and remote resources, helping keep your valuable information safe and available when you need it.

“How can we get started?” is the question you should be asking.

Considering Cybersecurity as Cloud Work Expands

When the pandemic forced many business users to move to remote work, it also forced the network security “boundary” to expand greatly and with great speed. Companies quickly adapted their tools and work so that it could be done somewhat effectively even as the employee working environment changed.  But new security models to match with new working models have not as quickly been adopted.

Business cloud workloads grew, by some estimates, as much as 20% just in the first 6 months of 2020. Yet many of those businesses electing to bring cloud working models to their business also made of the mistake of not expanding their security as they expanded the cloud network. This leaves systems and information vulnerable. Phishing, ransomware, credential theft and web app attacks have increased, catching businesses in their vulnerable states.

“In April to June of 2020 alone, security incidents increased by 188%.”

Even more than on-premises systems, it was the external cloud-based data and applications that were under attack because so many companies expanded their use of cloud services without enhanced security as part of the plan. Any expansion to include the cloud as network also significantly increases security risks. One report found that 35% of businesses made their cloud storage openly accessible to the public, allowing anyone to access it via the internet.

Don’t let your critical information be exposed or put at risk. When you begin using a cloud service, make sure to also address security for the new working mode or it could lead to lost or leaked information or a system breach.

Mendelson Consulting and NOOBEH cloud services take security very seriously. We help our clients keep their applications and data working properly and have a focus on methods to keep information safe regardless of what cloud you work on.
