Tips and Solutions of Endpoint Security

Managed Service Providers (MSPs) are an important part of the IT environment, providing the knowledge and the trusted partnerships that enable organizations of all sizes to embrace innovations made available by our era of digital transformation.

While there has never been a more exciting time to be an MSP, there are also many challenges MSPs must navigate to acquire and preserve long-lasting client relationships. Specifically, MSPs cite maintaining profitability (27%), bolstering growth (33%), and managing cybersecurity (30%) as some of their top business issues.

When it comes to managing cybersecurity, safeguarding client endpoints is a critical piece of the MSP service offering. To streamline the process, MSPs should have an endpoint security vendor that helps them overcome common issues that can cut into profits and lead to client churn, like prioritizing response efforts and managing security at scale.

Read this article to view 5 essentials that MSPs need from their endpoint security providers and for tips and solutions to ensure your MSP is successful in this area.

Your selected endpoint security vendor should ensure that you can streamline your client deployments, simplify your ability to prioritize your response efforts, and manage your clients at scale. Ultimately, your vendor should optimize the efficiency of your time and efforts so that you can continue to grow your business and maximize revenue.

Your vendor should:

  • Simplify deployment across multiple endpoints
  • Optimize time efficiency with prioritized alerts and responses
  • Automate isolation and remediation of infections
  • Make it easy to manage your clients at scale
  • Enable you to demonstrate value to your clients

Simple deployment

Whether you’re onboarding a new client or adding an endpoint for an existing one, deploying endpoint security software is an everyday occurrence for MSPs. If it doesn’t go smoothly, it sets a bad, first impression for new clients, and the lengthy deployment cycles can consume your valuable service time. Therefore, it’s important to prioritize partnering with an endpoint security vendor that makes new software deployments simple and fast.

Everything around us has become smart, like smart infrastructures, smart cities, autonomous vehicles, to name a few. The innovation of smart devices makes it possible to achieve these heights in science and technology. But, data is vulnerable, there is a risk of attack by cybercriminals. To get started, let’s know about IoT devices.

What are IoT devices?

The Internet Of Things(IoT) is a system that interrelates computer devices like sensors, software, and actuators, digital machines, etc. They are linked together with particular objects that work through the internet and transfer data over devices without humans interference.

Famous examples are Amazon Alexa, Apple SIRI, Interconnected baby monitors, video doorbells, and smart thermostats.

How could your IoT devices be vulnerable?

When technologies grow and evolve, risks are also on the high stakes. Ransomware attacks are on the continuous increase; securing data has become the top priority.

When you think your smart home won’t fudge a thing against cybercriminals, you should also know that they are vulnerable. When cybercriminals access our smart voice speakers like Amazon Alexa or Apple Siri, it becomes easy for them to steal your data.

Cybersecurity report 2020 says popular hacking forums expose 770 million email addresses and 21 million unique passwords, 620 million accounts have been compromised from 16 hacked websites.

The attacks are likely to increase every year. To help you secure your data of IoT devices, here are some best tips you can implement.

Tips to secure your IoT devices

1. Change Default Router Name

Your router has the default name of make and model. When we stick with the manufacturer name, attackers can quickly identify our make and model. So give the router name different from your addresses, without giving away personal information.

2. Know your connected network and connected devices

If your devices are connected to the internet, these connections are vulnerable to cyber attacks when your devices don’t have the proper security. Almost every web interface is equipped with multiple devices, so it’s hard to track the device. But, it’s crucial to stay aware of them.

3. Change default usernames and passwords

When we use the default usernames and passwords, it is attackable. Because the cybercriminals possibly know the default passwords come with IoT devices. So use strong passwords to access our IoT devices.

4. Manage strong, Unique passwords for your IoT devices and accounts

Use strong or unique passwords that are easily assumed, such as ‘123456’ or ‘password1234’ to protect your accounts. Give strong and complex passwords formed by combinations of alphabets, numeric, and not easily bypassed symbols.

Also, change passwords for multiple accounts and change them regularly to avoid attacks. We can also set several attempts to wrong passwords to set locking the account to safeguard from the hackers.

5. Do not use Public WI-FI Networks

Are you try to keep an eye on your IoT devices through your mobile devices in different locations. I recommend you not to use the public WI-FI network to access them. Because they are easily accessible through for everyone, you are still in a hurry to access, use VPN that gives them protection against cyber-attacks, giving them privacy and security features, for example, using Express VPN.

6. Establish firewalls to discover the vulnerabilities

There are software and firewalls like intrusion detection system/intrusion prevention system in the market. This will be useful to screen and analyze the wire traffic of a network. You can identify the security weakness by the firewall scanners within the network structure. Use these firewalls to get rid of unwanted security issues and vulnerabilities.

7. Reconfigure your device settings

Every smart device comes with the insecure default settings, and sometimes we are not able to change these default settings configurations. These conditions need to be assessed and need to reconfigure the default settings.

8. Authenticate the IoT applications

Nowadays, every smart app offers authentication to secure the accounts. There are many types of authentication methods like single-factor authentication, two-step authentication, and multi-factor authentication. Use any one of these to send a one time password (OTP) to verify the user who logs in the smart device to keep our accounts from falling into the wrong hands.

9. Update the device software up to date

Every smart device manufacturer releases updates to fix bugs in their software. These security patches help us to improve our protection of the device. Also, update the software on the smartphone, which we are used to monitoring the IoT devices to avoid vulnerabilities.

10. Track the smartphones and keep them safe

When we connect the smart home to the smartphone and control them via smartphone, you need to keep them safe. If you miss the phone almost, every personal information is at risk to the cybercriminals. But sometimes it happens by accident, makes sure that you can clear all the data remotely.

However, securing smart devices is essential in the world of data. There are still cybercriminals bypassing the securities. So make sure to do the safety measures to avoid our accounts falling out into the wrong hands. I hope these steps will help you all to secure your IoT devices.

If you have any, feel free to share them in the comments! I’d love to know them.

23 CentOS Server Hardening Security Tips - Part 2

If the setuid and setgid bits are set on binary programs, these commands can run tasks with other user or group rights, such as root privileges which can expose serious security issues.

Often, buffer overrun attacks can exploit such executables binaries to run unauthorized code with the rights of a root power user.

# find /  -path /proc -prune -o -type f \( -perm -4000 -o -perm -2000 \) -exec ls -l {} \;

To unset the setuid bit execute the below command:

# chmod u-s /path/to/binary_file

To unset the setgid bit run the below command:

# chmod g-s /path/to/binary_file

22. Check for Unowned Files and Directories

Files or directories not owned by a valid account must be deleted or assigned with permissions from a user and group.

Issue the below find command to list files or directories with no user and group.

# find / -nouser -o -nogroup -exec ls -l {} \;

23. List World-Writeable Files

Keeping a world-writable file on the system can be dangerous due to the fact that anyone can modify them. Execute the below command in order to display word-writeable files, except Symlinks, which are always world-writeable.

# find / -path /proc -prune -o -perm -2 ! -type l –ls

24. Create Strong Passwords

Create a password of a minimum of eight characters. The password must contain digits, special characters, and uppercase letters. Use pwmake to generate a password of 128 bits from /dev/urandom file.

# pwmake 128

25. Apply Strong Password Policy

Force the system to use strong passwords by adding the below line in /etc/pam.d/passwd file.

password required pam_pwquality.so retry=3

Adding the above line, the password entered cannot contain more than 3 characters in a monotonic sequence, such as abcd, and more than 3 identical consecutive characters, such as 1111.

To force users to use a password with a minimum length of 8 characters, including all classes of characters, strength-check for character sequences and consecutive characters add the following lines to the /etc/security/pwquality.conf file.

minlen = 8
minclass = 4
maxsequence = 3
maxrepeat = 3

26. Use Password Aging

The chage command can be used for user password aging. To set a user’s password to expire in 45 days, use the following command:

# chage -M 45 username

To disable password expiration time use the command:

# chage -M -1 username

Force immediate password expiration (user must change the password on next login) by running the following command:

# chage -d 0 username

27. Lock Accounts

User accounts can be locked by executing the passwd or usermod command:

# passwd -l username
# usermod -L username

To unlock accounts use the -u option for passwd command and -U option for usermod.

28. Prevent Accounts Shell Access

To prevent a system account (ordinary account or service account) to gain access to a bash shell, change root shell to /usr/sbin/nologin or /bin/false in the /etc/passwd file by issuing the command below:

# usermod -s /bin/false username

To change the shell when creating a new user issue the following command:

# useradd -s /usr/sbin/nologin username

29. Lock Virtual User Console with vlock

vlock is a program used for locking one multiple session on Linux console. Install the program and start locking your terminal session by running the below commands:

# yum install vlock
# vlock

30. Use a Centralized System to Manage Accounts and Authentication

Using a centralized authentication system can greatly simplify account management and control. Services that can offer this type of account management are IPA Server, LDAP, Kerberos, Microsoft Active Directory, Nis, Samba ADS or Winbind.

Some of these services are by default highly secured with cryptographic protocols and symmetric-key cryptography, such as Kerberos.

31. Force Read-Only Mounting of USB Media

Using blockdev utility you can force all removable media to be mounted as read-only. For instance, create a new udev configuration file named 80-readonly-usb.rules in the /etc/udev/rules.d/ directory with the following content:

SUBSYSTEM=="block",ATTRS{removable}=="1",RUN{program}="/sbin/blockdev --setro %N"

Then, apply the rule with the below command:

# udevadm control -reload

32. Disabling Root Access via TTY

To prevent the root account from performing system log-in via all console devices (TTY), erase the contents of securetty file by typing the following command terminal prompt as root.

# cp /etc/securetty /etc/securetty.bak
# cat /dev/null > /etc/securetty

Remember that this rule does not apply to SSH login sessions

To prevent root login via SSH edit the file /etc/ssh/sshd_config and add the below line:

PermitRootLogin no
