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.

Why is IPSEC used?
This allows IPSec to protect data transmission in a variety of ways. IPSec is used to connect a remote user to an entire network. This gives the user access to all IP based applications. The VPN gateway is located at the perimeter of the network, and the firewall too is setup right at the gateway.
What are the implications of IPSec connections for corporations?
What are the implications of IPSec connections for corporations, considering the very nature of this connection? Well, your employee will only be able to access the network from a single, authorized device. Security is further boosted by the enforcement of antivirus and firewall policies.

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.
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.
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.
Can VPNs be split horizon?
Unfortunately, fully maintaining this assumption is hard. Many VPNs are configured to prohibit a "split horizon"-that is, the ability to access the local physical network and the virtually connected enterprise network simultaneously.
