A security architect for a large, multinational manufacturer needs to design and implement a security solution to monitor traffic.

When designing the solution, which of the following threats should the security architect focus on to prevent attacks against the OT network?

1. Packets that are the wrong size or length
2. Use of any non-DNP3 communication on a DNP3 port
3. Multiple solicited responses over time
4. Application of an unsupported encryption algorithm

A company has hired a security architect to address several service outages on the endpoints due to new malware. The Chief Executive Officer's laptop was impacted while working from home. The goal is to prevent further endpoint disruption. The edge network is protected by a web proxy.

Which of the following solutions should the security architect recommend?

A Replace the current antivirus with an EDR solution.
B Remove the web proxy and install a UTM appliance.
C Implement a deny list feature on the endpoints.
D Add a firewall module on the current antivirus solution.

A network architect is designing a new SD-WAN architecture to connect all local sites to a central hub site. The hub is then responsible for redirecting traffic to public cloud and datacenter applications. The SD-WAN routers are managed through a SaaS, and the same security policy is applied to staff whether working in the office or at a remote location. The main requirements are the following:

1. The network supports core applications that have 99.99% uptime.

2. Configuration updates to the SD-WAN routers can only be initiated from the management service.

3. Documents downloaded from websites must be scanned for malware.

Which of the following solutions should the network architect implement to meet the requirements?

Options:

A Reverse proxy, stateful firewalls, and VPNs at the local sites
B IDSs, WAFs, and forward proxy IDS
C DoS protection at the hub site, mutual certificate authentication, and cloud proxy
D IPSs at the hub, Layer 4 firewalls, and DLP
