^{Common Vulnerabilities Associated With Remote Access}

1. Lack of established protocols. Last year, most IT security teams were forced to rapidly implement ad hoc solutions for remote access during an unpredictable time.
2. Unsecured networks. Now that your team is remote, your employees are all network administrators. Are their home networks secure?
3. Phishing. Social engineering has a new dimension now that employees aren’t in the same physical space. ...
4. Unauthorized apps. Unauthorized software is a common entrypoint for ransomware attacks. ...
5. Unauthorized access to devices. When the only devices capable of accessing sensitive data are in the same building, it’s relatively easy to keep them under lock and key.

What are the disadvantages of remote access client devices?

Remote Access Vulnerabilities Remote access client devices generally have weaker protection than standard client devices Many devices not managed by the enterprise No enterprise firewalls, antivirus, etc. Lack of physical security controls Remote access client devices may be used in hostile environments but not configured for them

Why is remote workforce security so important?

With a remote workforce, this problem becomes exacerbated by employees using personal devices and networks with much lower standards of security than their corporate-controlled alternatives, making it easy for attackers to access company data.

Are there security gaps in the remote workplace?

As the world adjusted to working from home, IT teams worked overtime to enable remote access for millions of employees. This transition went smoothly for most organizations, but many security gaps still remain almost a year later.

Why is it so hard to secure RDP remote connections?

The problem is that the same password is often used for RDP remote logins as well. Companies do not typically manage these passwords to ensure their strength, and they often leave these remote connections open to brute force or credential stuffing attacks. Unrestricted port access. RDP connections almost always take place at port 3389*.

What are the security risks of remote working?

What are the most important vulnerabilities in RDP?

Perhaps the top vulnerability of RDP systems, weak user sign-in credentials are an easy way for attackers to gain access to your network to deploy malicious software that steals or damages your sensitive data. Most desktop computers are protected by a password – but users can make this password whatever they want.

What are remote access attacks?

A remote attack is a malicious action that targets one or a network of computers. The remote attack does not affect the computer the attacker is using. Instead, the attacker will find vulnerable points in a computer or network's security software to access the machine or system.

Is remote access secure?

Remote access solutions could leave you vulnerable. If you don't have proper security solutions in place, remote connections could act as a gateway for cybercriminals to access your devices and data. Hackers could use remote desktop protocol (RDP) to remotely access Windows computers in particular.

How is RDP exploited?

RDP automatically connects to the service that was created first, so when a new user connects, the existing malicious pipe will be the one their machine automatically connects to. At that point, the attacker controls both ends of the pipe and can read, pass and modify data between the client and host.

Can RDP be hacked?

RDP has become a common way for hackers to steal valuable information from devices and networks. It is specifically vulnerable because of its ubiquity. Since so many businesses use it, the odds accessing an improperly secured network are higher and hackers have a better chance of breaking through.

What can hackers do remotely?

They can target any of the data stored there remotely. Passwords, SSNs, bank account details, text messages, photos—almost anything can get into the hands of the bad guys if you aren't careful enough and well-protected.

How do I protect my computer from remote access?

Open System and Security. Choose System in the right panel. Select Remote Settings from the left pane to open the System Properties dialog box for the Remote tab. Click Don't Allow Connections to This Computer and then click OK.

What is remote malware?

Remote access trojans (RATs) are malware designed to allow an attacker to remotely control an infected computer. Once the RAT is running on a compromised system, the attacker can send commands to it and receive data back in response.

How do you secure remote access to employees?

Require employees and vendors to use secure connections when connecting remotely to your network. They should: Use a router with WPA2 or WPA3 encryption when connecting from their homes. Encryption protects information sent over a network so that outsiders can't read it.

Can someone remotely access my computer when IT's off?

Without appropriate security software installed, such as anti-malware tools like Auslogics Anti-Malware, it is possible for hackers to access the computer remotely even if it is turned off.

What is a preferred security measure for remote access?

Virtual Private Networking (VPN) is often considered the best approach in securing trans-network communication.

Is RDP a security risk?

However, the highest risk is the exposure of RDP on the Internet, port 3389, and allowing it to traverse directly through the firewalls to a target on the internal network. This practice is common and should absolutely be avoided.

How do I check my RDP encryption level?

You can check the encryption level on target server where you got connected, open TS Manager and check the status of RDP connection, there you see encryption level.

How do I set my RDP encryption level to high?

Method 1Click Start, click Run, type tscc. msc in the Open box, and then click OK.Click Connections, and then double-click RDP-Tcp in the right pane.In the Encryption level box, click to select a level of encryption other than FIPS Compliant.

Why should RDP be disabled?

Introduction. It is always advisable to reduce security risks by disable unnecessary services. These instructions disable Remote Desktop Protocol (RDP) service, which is commonly leveraged by adversaries to attack Windows computers, such as the RDP Exploit BlueKeep.

1. Remote workforces are more susceptible to phishing scams

Without the proper protections on personal devices, remote workers can face greater threats from phishing attacks. Cyber criminals don’t care if personnel are working from home or in the office. Either way, they can trick workers into giving up login credentials—or completing a financial transaction—by posing as a message from a reputable company.

2. Out-of-date devices give hackers an easy in

Opportunistic hackers typically aim for well-known vulnerabilities. They’re particularly interested in known exploits for older, out of-date-devices. An organization which allows remote workers to use outdated personal devices puts their critical business information at great risk to cyber criminals.

3. Virtual private networks (VPN) can provide substantial protection, but you need the right one

VPNs are employed by a wide range of organizations to help bridge the gap between centralized networks and remote workers, allowing users to securely access business networks in an encrypted channel. However, consumer-grade VPN services can still be vulnerable to savvy hackers.

How does a VPN work?

A VPN establishes an encrypted tunnel between the system running the VPN client and a VPN server that then proxies traffic through the tunnel to the rest of the enterprise network. The system running the VPN client becomes, effectively, an extension of the enterprise network, existing inside that network's perimeter with access to resources generally equivalent to any other system on the enterprise network.

What is a VPN client?

The system running the VPN client becomes, effectively, an extension of the enterprise network, existing inside that network's perimeter with access to resources generally equivalent to any other system on the enterprise network. VPNs defend against attack via authenticated access control and isolation.

Why is it important to use a BYOD device?

BYOD can represent substantial cost savings to the enterprise over issuing enterprise-owned devices, and users are often happier because they can use familiar devices to get work done. Moreover, a device the user already has can be used immediately, without having to procure and ship the device to the user.

What is remote work?

Remote Work: Vulnerabilities and Threats to the Enterprise. For many organizations, COVID-19 dramatically changed the risk calculation for remote work. In January 2020, many enterprises viewed remote work with skepticism; by March, the choice for many was to become a remote-first enterprise or to shut down.

What is enterprise network?

Enterprise networks were traditionally accessed only on enterprise-provided equipment. This arrangement has permitted enterprises unrestricted access to monitor and configure the device precisely according to their risk profiles and mitigation strategies. It also has required the enterprise to purchase and maintain equipment. This has sometimes frustrated end users when the enterprise was unwilling to buy newer equipment, a problem that became particularly pronounced when smartphones and tablet devices entered the market.

Why are attackers moving early in 2020?

Unsurprisingly, in 2020 attackers moved early to capitalize on the rapid shift to work from home at numerous organizations, including federal agencies, such as NASA. The remote work environment is particularly appealing for attackers for several reasons. First, the home-network environment is not professionally managed.

Can a VPN be always on?

Many fewer VPNs, however, are configured to be "always on," meaning that the VPN endpoint effectively never interacts directly with the local network. If an attacker has persistence in that network, even brief access can expose the enterprise endpoint to compromise.

Why do companies use VPNs?

Historically, many companies deployed VPNs primarily for technical people needing access to critical technology assets. Not so much the case anymore – VPNs are often encouraged for all users as a more secure connection than home or public networks.

What are the risks of using a VPN?

Here are five top security risks that teams must deal with, as well as technology and user education best practices to keep users and data safe: 1. Weak remote access policies. Once attackers get access to a virtual private network (VPN), they can often penetrate the rest of the network like a hot knife through butter.

Why is it important to enforce access based on user identity?

Recommendation: It’s critical that companies enforce access based on user identity, allowing specific groups access to only what they need to get their jobs done, and expanding access from there on an as-needed basis.

What are the most important vulnerabilities in RDP?

These are the most important vulnerabilities in RDP: Weak user sign-in credentials. Most desktop computers are protected by a password, and users can typically make this password whatever they want. The problem is that the same password is often used for RDP remote logins as well.

What is RDP in computer?

What is RDP? RDP, or the Remote Desktop Protocol, is one of the main protocols used for remote desktop sessions, which is when employees access their office desktop computers from another device. RDP is included with most Windows operating systems and can be used with Macs as well. Many companies rely on RDP to allow their employees to work ...

What is the most severe vulnerability in RDP?

One of the most severe vulnerabilities in RDP is called "BlueKeep.". BlueKeep (officially classified as CVE-2019-0708) is a vulnerability that allows attackers to execute any code they want on a computer if they send a specially crafted request to the right port (usually 3389).

Why use SSO?

To reduce the prevalence of weak sign-in credentials: Single sign-on (SSO): Many companies already use SSO services to manage user logins for various applications. SSO gives companies an easier way to enforce strong password usage, as well as implementing even more secure measures like two-factor authentication (2FA).

What is Lock down Port 3389?

To protect against port-based attacks: Lock down port 3389: Secure tunneling software can help stop attackers from sending requests that reach port 3389. With a secure tunnel (e.g. Cloudflare Argo Tunnel) in place, any requests that do not pass through the tunnel will be blocked.

What is a port in a network?

*In networking, a port is a logical, software-based location that is designated for certain types of connections. Assigning different processes to different ports helps computers keep track of those processes.

Is BlueKeep wormable?

BlueKeep is wormable, which means it can spread to all computers within a network without any actions from users. The best defense against this vulnerability is to disable RDP unless it is needed. Blocking port 3389 using a firewall can also help.
