What's cyber security?

Computer security, cybersecurity or information technology security (IT security) is the security of computer systems in the theft of or damage to their own hardware, applications, or digital information, in addition to in the disruption or misdirection of their solutions they supply. The area is becoming more important because of greater reliance on computer technologies, the web and wireless system standards like Bluetooth and Wi-Fi, and as a result of development of "smart" devices, such as televisions, smartphones, and the numerous devices which constitute the"Internet of things". Due to its complexity, both regarding science and politics, cybersecurity can also be one of the significant challenges in the modern world.

What's cyber security?

Organizations face many threats to their data systems and information. Knowing all of the fundamental elements to cyber safety is the first step to fulfilling these threats.

Types of cyber security.

The reach of cyber protection is broad. The core regions are explained below, and some other fantastic cyber security plan must take all of them into consideration.

Critical infrastructure includes the cyber-physical systems which society is based on, for example, electricity grid, water purification, traffic lighting and hospitals. Plugging a power plant to the world wide web, as an instance, makes it vulnerable to cyber attacks. The solution for associations accountable for critical infrastructure would be to carry out due diligence to safeguard recognize the vulnerabilities and protect from them. Everyone else must evaluate the way an attack on critical infrastructure that they rely on could impact them and develop a contingency plan.

Network security guards against malicious intrusion in addition to malicious insiders. Ensuring network security frequently requires trade-offs. By way of instance, access controls like additional logins may be required, but slow down productivity. Tools used to track network safety create a great deal of information -- so much that legitimate alarms are often overlooked. To help better handle network security monitoring, safety teams are using machine learning how to flag abnormal traffic and alert to risks in real time.

The business's move to the cloud generates new safety challenges. By way of instance, 2017 has seen nearly weekly information breaches from badly configured cloud cases. Cloud suppliers are creating new safety tools to help business users secure their information, however, the bottom line remains: Moving into the cloud isn't a panacea for performing due diligence in regards to cyber security.

Application security (AppSec), especially web application security, has become the weakest technical point of attack, but few organizations adequately mitigate all the OWASP Top Ten web vulnerabilities. AppSec begins with secure coding practices, and should be augmented by fuzzing and penetration testing. Rapid application development and deployment to the cloud has seen the advent of DevOps as a new discipline. DevOps teams typically prioritize business needs over security, a focus that will likely change given the proliferation of threats.

IoT describes a huge array of crucial and non-critical cyber physiological systems, such as appliances, sensors, printers and safety cameras. IoT devices often ship in an insecure condition and give little to no security, posing risks to not just their customers, but also to other people online, since these devices frequently find themselves part of a botnet. This presents special security challenges for the home users and society.

Email threats are becoming an increasingly large problem, both for companies and individuals. As our email addresses and personal information become more widely spread, it becomes easier to find this information online, which allows malicious actors to discover routes of attack more easily. For businesses, attacks such as phishing email threats, malware threats, and darknet email threats can leave vulnerable data and systems exposed and can cause major reputational and monetary losses.

One of the best ways to fight threats is to use an appropriate tool. Most people think of antivirus software and scanning tools in this context, but broader tools can protect your business in a much more comprehensive way, while providing other useful features. SolarWinds® Identity Monitor and SolarWinds Server & Application Monitor (SAM) are at the top of my list for preventing email threats from stealing your business information and gaining critical access.

Email Threats Definition

A definition of email threats is hard to form, because there are so many different kinds of threats, and the routes attackers use change constantly. Some of the most common email threats come through deception, impersonation of trusted entities, and the exploitation of private information to encourage people to click on links or download attachments. Once these attachments are downloaded, malware can be installed; if a link is clicked on, the user may be forwarded to a fake login page, at which point their credentials are stolen.

Types of Email Attacks in 2020

Many types of email attacks are occurring in 2020, but a few stand out more than others in terms of their danger to the user and the likelihood of occurrence.

common email threats

Phishing Email Threats

Phishing emails involve an attacker pretending to be someone else—such as a bank or a service you’ve subscribed to—with the aim of tricking you into opening their email. The fundamental marker of a phishing email threat is the sender appears to be a trusted entity, but the email contains a malicious link.

The link can lead either to a download of malware or to a fake webpage, such as a bank login page. If you then log in to your bank through the link, the malicious attacker gets your login credentials. In many cases, phishing attacks are used to gain entry to corporate networks—for example, by compromising employee accounts and allowing the attacker to bypass security measures.

Malware Threat Email

Like phishing email threats, malware can be sent through an email. You’ll know it’s malware if, for example, you don’t recognize the sender, the email has an attachment, the email subject field is blank, or the email asks you to confirm or review information using an attachment.

Generally, once you open this attachment, a piece of malware will be downloaded onto your computer. If you unsuspectingly open the attachment and the contents of the file or document look different than what you expected, this may also indicate malware.

Darknet Email Threat

A darknet email threat is a common scam in which someone emails you pretending to be a person from the darknet—i.e., the “underground” part of the internet. Often, the email appears to have been sent from the user’s own email address. The sender states they’ve hacked your email and have been monitoring your computer for some time, accessing information on your contacts, computer use, browsing history, and so on. The sender then claims they have compromising information or videos of you and demands money to keep them from sending this information to all your contacts. This kind of threat preys on people’s fear of being exposed in their private lives and activities.

Generally, this kind of email is just a scam, but it’s possible the sender has either spoofed your email address (i.e., made it appear they sent the message from your own email address) or obtained your email, name, and password from a compromised website. It’s important to know when your credentials or identity has been compromised, so you can create new passwords and protections.

Options for Defense

Regardless of how you define an email threat, the options for defense are also rapidly expanding and developing.

There are numerous ways to defend against email threats, including implementing antivirus and mail scanning software, instituting internal policies, and using multiple levels of authentication on your account (e.g., logging in both online and via your phone). There are two basic levels to focus on when implementing security measures: first, the point before the user has received or opened the email; and second, the point at which their credentials may have been compromised.

Organizational Policies

Organizational policies play a large role in preventing users from opening suspicious emails. Any such policy should include clear and thorough education on how to recognize an email attack, and what to do if you suspect someone has targeted you. In addition, businesses should have clear policies on what staff should do if they accidentally open an email attachment or link.

Tools and Software

Another factor is using software to stop suspicious emails from reaching users. You should have in place some kind of software to identify malware attacks and suspicious emails, and a tool to detect unusual activity on the mail server.

My preferred tool for protecting your business from email attacks is SolarWinds Server & Application Monitor (SAM). SAM is both email monitoring software and a mail server monitoring tool, which can help detect any suspicious activity before a breach occurs. For example, it can detect sudden email traffic spikes, which can indicate an attack is occurring.

SAM

You can access a free trial of SAM for up to 30 days.

Once a breach has occurred, it’s important to determine which accounts and credentials have been exposed, so relevant passwords and access details can be changed as quickly as possible. My top choice for protecting and securing account credentials is SolarWinds Identity Monitor, a web-based tool that allows you to enter your email address to check for corporate credential leaks. Identity Monitor notifies you when any of your employees’ credentials have appeared in a data breach or data leak posted on the dark web. This type of careful monitoring means if an attacker steals your credentials, you’ll be notified, ideally before the attacker shares the credentials with other malicious entities.

SolarWinds Identity Monitor is an annual subscription service. You can set it up to monitor for potential issues before they occur, with the option of adding domains or private emails to a “watch list.” In addition, IP addresses can be set up for monitoring and compared to known botnets: if you see one of your IP addresses linked to a botnet, you can identify this computer has had malware installed on it.

Best Tools to Fight Email Threats

Effectively fighting email threats requires a combination of employee and organizational education, wide use of tools, and security at multiple levels of your business. By implementing SolarWinds Identity Monitor and SolarWinds Server & Application Monitor, you can be sure you’re fighting threats comprehensively, and protecting each aspect of your infrastructure. Finally, make sure you have well-thought-out response and management policies set up in your organization, to ensure problems are escalated to the right person in a timely manner.
