8 remote access security risks and how to prevent them - SearchNetworking
Just when network teams thought they had their networks under control, everything went sideways because of the coronavirus crisis. Many people were caught off guard as they were forced to deploy and support a remote workforce like no one ever imagined.
What should security teams do if on-premises network and email security mechanisms are no longer available?
Recommendation: If some on-premises network and email security mechanisms are no longer available, security teams should double down on educating users to identify phishing attempts and to choose strong, unique passwords, encouraging the use of a password manager. They should also implement client certificates and multi-factor authentication in order to prevent attackers from gaining access through unsecured devices.
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.
What is XDR in security?
Recommendation: Rather than invest in point solutions, consider security platforms that maximize integration between systems, limiting the amount of switching between tools and providing visibility into all data – including remote user activity. Extended detection and response (XDR) not only protects endpoints, but also applies analytics across all your data to find threats like unusual access or lateral movement, and simplifies investigations by stitching together data and identifying the root cause.
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.
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 is Wildfire malware analysis?
Resources: Learn how the cloud-delivered WildFire® malware analysis service – which is built into Cortex XDR and many other Palo Alto Networks products – aggregates data and threat intelligence from the industry’s largest global community to automatically identify and stop threats. Additionally, URL Filtering blocks access to malicious sites to help prevent phishing attacks.
What is dial up remote access?
Dial-up remote access requires only plain old telephone service (POTS) or ISDN lines, and allows users to make connections to many resources, from corporate headquarters, to bulletin board services, to the Internet/Intranet. Dial-up remote access also allows travelling or telecommuting remote users to connect to their network as if they were located on-site.
What is dial up connection?
A dial-up connection between two networks is termed as an LAN-to-LAN connection . In most cases, remote office locations will connect to a main corporate network at a central location. In other cases, one small office may connect to another small office or to a site where services such as Internet access or information services are provided.
What is remote node access?
Remote node network access allows remote users to connect to a network using a modem. Remote node users are typically mobile or telecommuter users who run a remote client software package on their PC or workstation giving them network access through a dial-up server. Remote node access to the network has become easier because of the TCP/IP or IPX support that's been built into Windows95 and other operating systems. Most of the current demand for such services involves either IP (Unix) or IPX (Novell NetWare) protocols.
Why is modem pooling important?
For the network manager, modem pooling provides the added conveniences of easy maintenance because all modems are in one location, and easy management as remote access servers typically have more robust network management than modems. Protocols such as IP and IPX support the sharing of modem resources through software tools available under a host or network operating system ( the remote access device that supports these applications provides ever greater value. INT14 support under IPX and redirection of serial port output to a communications port using IP and IPX protocols are essential features that this type of software should support.
Why is remote control important?
Remote control is useful when a user needs a lot of processing power or number crunching capability, because only the serial information sent to the keyboard, mouse and display need pass over the dial-up link. The drawback of this approach is that the user can only view the information and cannot transfer files or obtain data to be processed on their remote system. Remote control is more frequently used with the IPX (NetWare) protocol; IP users can use terminal servers to achieve the same result when a multi-user host is available.
What is the key attribute of remote access?
No matter what remote access strategy you plan to implement, one key attribute that requires the greatest attention, is that of providing controlled access to your important/proprietary data. When a strategy for networking involves dial-up technology, issues of network security become very important. Each modem is a potential gateway for uninvited users, either by chance or malicious intent, to gain access to the attached network.
What is routing in network?
When a connection is made to another network, routing is the key to this type of functionality ( when a user on the network requests connection to a resource available only on another network, the remote access device recognises the need to dial another network and then automatically dials up the appropriate remote site according to a stored profile. Once the connection has been established, the remote access device will monitor the connection according to the parameters established by the network manager.
Why is remote work so attractive?
The remote work environment is particularly appealing for attackers for several reasons. First, the home-network environment is not professionally managed. Most critically, this means that many more systems on home networks are not patched regularly, and a number of them are out of date with respect to vulnerability mitigation. Some may even be treated by their manufacturers as end-of-life (EOL) products, and will never receive mitigations even when serious vulnerabilities are found.
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 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.
What is persistence on an enterprise network?
To persist on an enterprise network, an attacker who has exploited a system must avoid detection and resist remediation. Here too, the home network is friendlier to the attacker; threat detection is typically nearly absent, and remediation incidental, such as when a PC is reinstalled or retired because it is running slowly.
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.
Is remote work a threat?
Attackers have been aware of remote work as a threat vector for some time. Mandiant reported a 2015 trend of attackers hijacking VPN connections, even those protected with multi-factor authentication (MFA). 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.
Is availability a security property?
In such an environment, it's understandable to look for ways to do more with less. Availability is a security property, and few things threaten availability more than insolvency.
