Radio Silence is a Mac program that enables you to monitor your network activity and prevent unneeded. A network utility for the rest of us. * Net Monitor graphs a histogram of network activity of local and remote computers in a floating window, the Dock, the Menu Bar or in a regular window. PRTG Network Monitor monitors network availability and network usage using a variety of protocols including SNMP, Netflow, and WMI. It is a powerful tool that offers an easy to use web-based interface and apps for iOS and Android. Cacti® is a network monitoring tool that allows you to collect data from almost any network element, including routing and switching systems, firewalls, load balancers, and servers, and put that data into robust graphs.
PRTG Network Monitor from Paessler. PRTG Network Monitor software is commonly known for its advanced infrastructure management capabilities. All devices, systems, traffic, and applications in your network can be easily displayed in a hierarchical view that summarizes performance and alerts. Cacti® is a network monitoring tool that allows you to collect data from almost any network element, including routing and switching systems, firewalls, load balancers, and servers, and put that data into robust graphs.
Any malware powerful enough to overcome the defenses that Apple built to resist incursions may also be powerful enough to hide its traces. That’s not quite an axiom of security, but it’s generally true. If an attacker of any sort creates software designed to attack your system quietly, it typically tries to prevent security software and any other kind of inspection from noticing.

That’s very, very hard, and any exploit that’s sufficiently good at being entirely invisible is likely also good enough for a hacker to sell for a million dollars, with the advantage that the sale is probably legal in most places, and thus better than distributing malware that steals financial credentials or holds files for ransom. (I am not a lawyer, and that’s not legal advice.)
Such exploits, once discovered, are fixed at high priority by operating system makers, giving them sometimes short windows of utility. The more widely used the exploit is, the less likely it will remain available to use.
Unless you’re a highly valuable targeted individual, it’s more likely that what you’d see is malware that doesn’t hide its traces that well because most people aren’t set up to look for it. This can be especially true in macOS and iOS. Most macOS users don’t run software capable of spotting malicious behavior; they rely on Apple. iOS can’t run anti-malware or other monitoring software at all. And Apple has stayed on top of the biggest risks to iOS as they’ve been discovered, whether as zero-days (found in the wild before being patched) or ahead of widespread use.
Because Apple doesn’t lock down macOS as tightly as iOS, it’s thus more vulnerable to less-severe assaults. To forestall a large category of attacks, Apple added a powerful baseline feature starting in OS X El Capitan (10.11). System Integrity Protection (SIP) locks down major directories associated with macOS and Apple’s preinstalled apps.
But there’s a lot of havoc that can be wrought without accessing files in those paths, and while SIP appears well designed, it’s absolutely a target of hackers. To my knowledge, it hasn’t been broken through yet, but that never means it can’t.
This column is another entry in my series of how to deal with security as if you woke up and were a dissident in your own country. Assuming the unlimited resources of a government agency or security apparatus, any vulnerability that can be found will be, and it will be used as skillfully as possible for as long as possible. Protecting against such vulnerabilities helps you fight malware as well as government-led attacks.
Multi-pronged resistance
In the olden days, I used to run firewall software, anti-virus software, and some other protective extensions. OS X was young, and there had been malware for System 7, 8, and 9. However, Apple had a very small percentage of the market share, and hadn’t built OS X to allow its email software to execute code. Security through obscurity worked.
All of those different pieces of monitoring and protection software did slow things down. I gradually stripped them off, as I felt Apple had improved the OS or certain kinds of threats disappeared. Now, I find myself in the reverse position, layering amulets one on top of each other.
There’s still the risk of adverse interaction and system slowdowns, but the kind of monitoring that will serve you best integrates at a level where it’s examining what’s happening instead of churning away at tasks.
If you want to monitor and block potential adverse actions, I recommend these four areas, some of which have a single product offering, often cheap:
Network monitoring.Little Snitch ($35) is a sort of firewall, although it’s more accurately an app-based network activity filter. You can whitelist and blacklist permitted network behavior by apps and system components, and have an alert spring up before new ones are allowed. I reviewed the initial release of the current version in 2012; it’s been updated all the way to 3.7.1 since, and works with Yosemite, El Capitan, and Sierra (10.10, 10.11, and 10.12).
Little Snitch can prevent malicious apps from reaching out to command-and-control systems they use to download full malware payloads or transmit information back to an attacker. Firewall apps from other companies take a different approach to a similar end, but I prefer Little Snitch’s conceptual framework.
File-access monitoring. Designed in part to block potential ransomware from gaining a foothold in macOS, Little Flocker ($15 to $25) works at a system level to control which apps and system components have access to which volumes, files, and directories. You can set up rules or have it learn your system’s behavior, and you’re prompted to allow or deny attempts that fall outside permitted actions you defined.
Little Flocker operates under the reasonable proposition that few apps need unlimited access to read, write, or otherwise modify every user-accessible file on all mounted drives. Ransomware gets called out, because such malware encrypts typically only user documents, which have less protection than system files. But apps also shouldn’t be trying to read files other than those you point it at—especially an app the name of which you don’t recognize or know why it would be running.
There’s nothing else quite like it available. I wrote up a detailed preview of the 1.0 release in November. The app is $15 for personal use (up to five computers) or $25 for a single-user business license. it works in El Capitan and Sierra.
Persistent software installs.BlockBlock (free, still in beta) is another nearly unique app, monitoring for attempts to create system entries that allow software to be persistent, or relaunched at every reboot. One of the first thing malware does is try to make sure that even if it’s killed off during a session, whenever a computer reboots, it simply launches again. You can allow or block such attempts. (I wrote about BlockBlock in the same article that covers Little Flocker.)
Mic and video activity. Keeping outsiders from gaining access to your Mac’s mics and cameras is key in ensuring privacy, and that kind of access is more likely from government players trying to surveille you than plain old malware operators, who just want to steal. I’ve written two columns about this, one about audio and one about video.
Several apps, free and paid, can monitor whether an audio or video source is being tapped, but because that monitoring relies on the system properly reporting what’s happening, they’re much more likely to be disrupted by clever software. This is why those most at risk of A/V snooping remove mics and video (or put tape over a video camera).
You may feel like you’re being watched
Too much monitoring can be irritating. I was just watching some of the old “I’m a Mac/I’m a PC” ads on the 10th anniversary of the launch of that multi-year campaign, and I saw the one that ridiculed Microsoft Vista’s excessively interferring security permission system.
No Mac user wants to relive that. But the joy of the two more frequently invoked of the four categories I note above is that they’re rules-based and you train them. There’s a learning period after which you’re asked less and less often, because new behavior only arises from installing new apps—or from malware. The other two categories only intrude when either something happens: software tries to install a persistent component or A/V hardware gets invoked.
Drawing program for mac. I’m using two of the above regularly (A/V monitoring and Little Flocker) and am easing into installing the other two. I know a number of people who run all four. The lack of overlap between them should keep bad interactions low.
What Is Network Monitoring?
To some it might feel like the local area network (LAN) has lost some of its importance. After all, it's old for a tech buzzword and these days everything is running from the cloud, so how important are local networks anyway? The answer is: Probably more than ever. The LAN is now the 'last mile' in terms of cloud service delivery, and if you're one of those businesses that's utilizing 5, 10, or more cloud services as everyday work tools for your employees, then that's a lot of network traffic competing for LAN bandwidth.
Today more than ever, an unreliable data network can literally bring a business to a standstill. For instance, if the systems attached to your network can't get an IP address by using Dynamic Host Configuration Protocol (DHCP), then they won't be able to communicate with any other system. Similarly, if Domain Name System (DNS) isn't functioning properly, then your systems won't be able to look up the address of any system on the internet. The way in which you manage bandwidth and network utilization will directly affect the productivity of all users connected to your corporate network. To help you, we've tested and compared 10 of the top network monitoring software solutions available today. Most are cloud-based and all of them can help you keep your users connected and your network pipes safe.
Some of those services cross over into the category of infrastructure due to the criticality of the service. Monitoring services such as DNS then becomes more of an infrastructure management issue as opposed to a network consideration. DHCP probably fits the same description, although the managing of a DHCP service would be something for which a network administrator would typically be responsible.
Simple Network Management Protocol (SNMP) was first introduced in 1998 under Request For Comments (RFCs) 1065, 1066, and 1067. SNMPv2 and SNMPv3 have, for the most part, replaced the initial version and have seen widespread adoption across a variety of platforms. While SNMP is most frequently associated with networking, you can also configure operating systems (OSes), to include Microsoft Windows, to respond to SNMP commands. A key consideration for network management tools should be how they use SNMP to accomplish their tasks.
If you really want to know what's happening on your network, then you'll need to learn something about network flows. NetFlow was originally introduced for Cisco routers, providing the ability to analyze IP network traffic entering or exiting a specific interface. Flow data is sent to a collection point (typically a system running a database) to make query-based analysis easier. Other switch manufacturers followed suit, along with other similar sampling tools such as sFlow. A large number of networking hardware vendors including Arista Networks, Brocade Communications Systems, Hewlett-Packard, and others provide native sFlow support. You can find a full description of sFlow under RFC 3176.
Important Features
A number of key features stand out as specific needs to adequately fulfill the role of network management. For one, from an administrator's perspective, it's nice to have visual graphics that give you a quick overview of the current system status. Having the ability to tweak the arrangement of graphical elements on a dashboard is an added plus. Providing a mechanism to alert someone of a problem is necessary across the board.
IP Address Management (IPAM) has become a vital capability for many large organizations. Keeping track of statically assigned addresses, along with a large number of DHCP pools, can't be adequately managed with a manual system. Integrating IPAM with a network management tool just makes sense as the same person quite frequently handles both functions.
Automation is the key to managing large numbers of devices. The more you can automate small administration tasks, the more efficient the process becomes. Automated alerting and repair fall into this category and represent a key differentiator between products. Add to that the ability to remotely connect to your monitoring system, and you have the makings of a solid product.
Software-Defined Networking (SDN) is a hot topic and not without a significant level of confusion—unless you happen to be either a vendor or a technologist with a vested interest. At a very high level, the term SDN is used to describe the functional separation of the network control plane and the forwarding plane, making it possible to dynamically configure data paths for optimum performance. None of these products really get into SDN, except at the top level of monitoring the performance of a switch.
How We Tested
In this roundup, we call out several areas to help focus the evaluation. While installation and setup is something you really only do once, it's still an area of interest. For the network management category, the initial configuration may include making changes to your switches in order to enable the transmission of NetFlow or sFlow data. Changes to production switches typically require a significant amount of justification and approval prior to implementation. It would be prudent to prove any of these test methods on a small test network before moving onto any larger environment.
That being said, we used an HP Procurve 3800 managed switch as the primary sFlow source. Enabling sFlow on the switch required the entry of a number of commands at the switch command line interface (CLI) over an SSH connection. We also had to upgrade the switch firmware to the latest version for everything to work correctly. At least one product (ManageEngine OpManager) provided a script to enable sFlow along with a one-page 'how-to' document to do that for you.

From an administrator's perspective, the user interface (UI) must be easy to navigate and customize. It should quickly present any problem areas and allow an operator to drill down for more specifics without a huge number of clicks. The customization of the UI and management of features must not require a programmer to make it properly work. Alerting is a basic requirement, with the ability to customize the priority and delivery an equally important feature.
Reporting should be equally as easy to administer. Creating a new report with a query specific to the information of interest should not require a database administrator. Extra points are given here for useful graphics and multiple export formats. Role-based access may not be a big deal for a small organization but it would be for a group with multiple IT administrators.
Free Network Monitoring Software For Mac
The bottom line with network management is to keep the network smoothly functioning, with an eye on overall usage. Having the ability to see trends and potential problems can help stave off any future problems and add value to any product.
How to Buy
The first step for any IT project is to define the requirements. For network management tools, the foundational pieces include the ability to see detailed information about key pieces of hardware such as switches and routers. Many organizations don't have the staff to monitor computer screens 24/7. Automated alerting and remediation would be a key requirement in that case to help reduce the administrative manpower required. Trend-based reporting and monitoring help determine utilization levels and identify potential bottlenecks before they become a problem. Good reporting tools would be another requirement, to include the ability to create customized reports and queries.
